UNPACKING VALVE FROM SHIPPING CONTAINER

Check the packing list against materials received, while unpacking the valve. The Packing List describes valve and accessories in each shipping container.

When preparing valves and actuators for lifting, be sure to use certifi ed lifting equipment and proper rigging. Position anylifting straps to avoid damage to the tubing and mounted accessories.

INSTALLATIONWARNING Refer to the General and Scope sections of this Manual (See Page 2) prior to beginning Installation.

Before installing these valves, be sure to inspect the fl ange mating surfaces on both the valve and the pipeline fl anges. Clean dirt, welding chips, scale or other foreign material from the line and fl ange surfaces. Check the pipeline fl anges for alignment and look for signs of gasket leakage through the line fl anges, make repairs if necessary.

The Model 570 requires the use of long studs that span the length of the valve and through both line fl anges. The body casting is designed to utilize the long studs to assist in centering the valve in the line. Models 571 & 573 use shorter studs to connect the valve fl anges with the line fl anges, the studs do not center the valve in the pipeline.

CAUTION Only well trained experienced technicians should perform these procedures. Be sure to use safe work practices and lockout procedures. Always be aware of the hazards of spring-loaded actuators. Be sure that they are in the failed (de-energized) position before performing any maintenance procedure. These valves have dangerous pinch points. Never put your hands inside the valve unless you are certain that the ball cannot rotate. Use safe work practices and lock out procedures when isolating valves and actuators. Always be aware of fl ammable instrument gas.

1 Install the valve with fl ow through the valve in the direction as indicated by the arrow on the valve body (standard fl ow direction has the seal protector ring (Key 10) facing upstream). The valve assembly may be installed in any position unless limited by vibration considerations, See Figures 5 & 6. NOTE: Excessive wear to the valve may be caused if the valve is installed with the drive shaft (Key 16) in a vertical orientation.

WARNING Keep hands, hair and clothing away from all moving parts when operating the valve. Serious injury can result from failure to do so.

Model 570 Installation (Refer to Figures 2 and 3, and Tables 8, 10, and 11 for fl ange stud (Key 32) dimensions)

1 Coat the threads of two fl ange studs with anti-seize lubricant and install them into the fl anges before placing the valve body. The two studs should be placed appropriately to help center the bottom of the valve body, See Figure 3.

2 Set the appropriate line gaskets in place.

3 Insert the valve into line centering the bottom of the valve body between the two studs installed in Step 1. Lubricate the remaining studs with anti-seize compound and install them. Make sure the valve is properly centered between the pipeline fl anges and then tighten the fl ange studs evenly in a criss-cross pattern to the correct torque specifi cations.

Models 571 & 573 Installation (Refer to Figures 2 and 3, and Tables 9, 10, and 11 for fl ange stud (Key 32) dimensions)

NOTE Longer fl ange studs are needed for the seal protector ring (Key 10) side of the valve. DO NOT use standard length studs for the seal protector side of the valve, see Table 9.

1 Lubricate the fl ange studs with anti-seize compound and have them ready to hold the valve in line.

2 Set the appropriate line gaskets in place.



P-570M1217B 9


INSTALLATION (Continued)

Models 571 & 573 Installation (Continued)

3 Insert the valve in line and make sure the valve is properly centered between the pipeline fl anges. Tighten all the fl ange studs and nuts evenly in a criss- cross pattern to the correct torque specifi cations.

Air Piping Standard actuators are designed to accept a 1/4” (6 mm) NPT connection. Use 3/8” OD tubing (or equivalent) for all air lines. Always follow good piping practices when installing piping or tubing, install all required line vents, valves, drains, seals, and fi lters. For more information refer to the appropriate actuator instruction manual for your product.

WARNING Property damage, environmental harm, and personal injury can result from the use of supply gas other than clean, non-corrosive, oil and moisture free air. Do not exceed the supply pressure indicated on the serial plate located on the yoke of the actuator.

PERIODIC INSPECTION CAUTION Use safe work practices and lock out procedures when isolating valves and actuators! Always be aware of fl ammable instrument gas!

1 Avoid personal injury from sudden release of process pressure! Before performing any maintenance operation:

A Disconnect any power supply media lines providing air / gas pressure, electric power, or a control signal to the actuator. Ensure the actuator cannot suddenly operate the valve.

B Isolate the valve from process pressure with bypass valves or completely shut off the process. Relieve process pressure, and drain the process fl uid from the up and down stream of the valve.

C Vent the pneumatic actuator loading pressure and relieve any actuator spring preload.

D Use Safety lock-out procedures to be sure that the above provisions stay in effect while you complete the work on your equipment.

2 Check for process fl uid leakage to the atmosphere through the packing and (if equipped) any NPT connection.

3 Examine the valve for damage caused by corrosive fumes or process drippings.

4 Clean the valve and repaint areas of severe oxidation.

6 Ensure all accessories, mounting brackets and fasteners are secure.

7 Clean any dirt and foreign material from the stem.

PACKING MAINTENANCEIf the packing is leaking, and tightening the packing fl ange does not stop the leak, then it is recommended that you remove the valve from the line. Refer to Valve Disassembly / Packing Removal for maintenance instructions. For live loaded packing, refer to the live loaded packing instructions for proper adjustment procedures.

DISASSEMBLYCAUTION Only well trained experienced technicians should perform these procedures. Be sure to use safe work practices and lockout procedures. Always be aware of the hazards of spring-loaded actuators. Be sure that they are in the failed (de-energized) position before performing any maintenance procedure. These valves have dangerous pinch points. Never put your hands inside the valve unless you are certain that the ball cannot rotate.

1 Isolate the valve from the process by completely shutting off the process pressure or use bypass valves if necessary. Drain the process fl uid from upstream and downstream of the valve.

2 Disconnect any power supply media lines providing air / gas pressure, electric power, or a control signal to the actuator. Isolate and bleed off any instrument gas from the actuator and instruments. Ensure the actuator cannot suddenly operate the valve.

CAUTION Use safe work practices and lock out procedures when isolating valves and actuators! Always be aware of fl ammable instrument gas!



P-570M1217B 10


DISASSEMBLY (Continued)

3 Secure the valve and actuator assembly and remove them from the pipeline by removing the fl ange studs (Key 32).

Valve / Actuator Disassembly 1 Replacing the ball seal can be accomplished without removing the actuator. Place the valve assembly on a fl at work surface that can support the assembly weight, the valve seal protector ring (Key 10) should be facing up. Relieve any actuator spring preload and refer to the appropriate actuator instruction manual for actuator disassembly instructions.

2 Take note of the ball position relative to the actuator lever where the spline of the shaft goes through. This will assure proper ball position during reassembly. A digital camera works well for this. You can remove the travel indicator arrow, (DFR 026 and DFR 047) or the cover plate, (DFR 070, DFR 156 and DFR 220) from the actuator and mark the shaft and lever with a punch or take a digital picture showing the ball position and the lever position. For Dyna-Flo Model DFR 026 actuators there is no clamp on the lever. For the DFR 047, DFR 070, DFR 156 and the DFR 220 you will have to remove the cover and loosen the clamp on the lever.

3 Remove the actuator mounting bolt (Key 30) and slide the valve body assembly from the actuator. This may require the use of a pry bar between the body and the actuator mounting pad. The lever on the DFR 070, DFR 156 and DFR 220 will sometimes bind when trying to remove the valve body assembly. A wedge driven into the slot in the lever will help to loosen the clamp on the lever. CAUTION: Using a hammer to drive the actuator off of the valve shaft can seriously damage the valve.

WARNING To Avoid personal injury and property damage use caution when separating the actuator from the valve body, during removal the valve ball may rotate in the body.

Packing Removal For live loaded packing, refer to the Live Loaded Packing instruction manual (P-LLPR) for assembly instructions.

1 Remove the packing nuts (Key 27), note any corrosion or roughness in the threads. Remove the packing follower (Key 23) by sliding it over the drive shaft (Key 16).

NOTE Valve shaft packing (Key 22) may be removed without removing the drive shaft (Key 16) from the valve however it is easier to remove the packing and inspect the valve shaft and packing bore when the drive shaft is removed. Refer to Ball / Shaft Removal for drive shaft disassembly instructions.

2 Using a mechanics pick set or wire hook, remove the packing box parts (Keys 21 & 22) from the packing bore. Be extremely cautious not to damage the drive shaft or the packing bore while removing packing as this will cause new packing to leak.

3 Inspect all packing parts, drive shaft, and packing bore for damage, polish or replace as necessary. Refer to Assembly / Packing for packing assembly instructions.

Ball Seal Removal NOTE During seal removal, the valve actuator may remain mounted to the valve body.

1 Rotate the valve ball (Key 3) to the open position. For PTFE Composition Ball Seals

A Remove the seal protector ring screws (Key 12 &

12A) and seal protector clips (Key 11 & 11A). Carefully remove the seal protector ring (Key 10) and gasket (Key 9). B Remove the seal (Key 5) from the valve body. For 1, 1-1/2, & 2 inch valves remove the back-up ring (Key 4) as well.

C Clean and inspect all seating, sealing, and gasket surfaces for damage. If there is excessive wear or damage to the seal ring, check the valve ball (Key 3) for damage in corresponding areas. It is also a good opportunity to inspect the fl ange gasket surfaces for damage while the valve is out of line.



P-570M1217B 11



Ball Seal Removal (Continued)

For Metal Ball Seals

A Remove the seal protector ring screws (Key 12 & 12A) and seal protector washers (Key 11A). Carefully remove the seal protector ring (Key 10) and gasket (Key 9). NOTE: Caution when removing the seal protector ring the metal ball seal can fall out and damage itself or the ball.

B Carefully remove the metal ball seal (Key 6) by pushing it away from the fl ange gasket side of the seal protector ring.

C Remove the wave spring (Key 8) and the radial seal (Key 7) from the seal protector ring.

D Clean and inspect all seating, sealing, and gasket surfaces for damage. It is also a good opportunity to inspect the fl ange gasket surfaces for damage while the valve is out of line.

CAUTION If the bearings (Key 20) require removal special tooling may be required. In most cases the bearings can be removed with a standard punch, a standard punch may also damage the bearings. If the bearings are to be reused, see Figures 10 & 11 and Table 13 for drawings and information on bearing removal tools that will not damage the bearings.

NOTE Before the bearings can be removed from the valve both the drive shaft (Key 16) and follower shaft (Key 13) must be removed from the valve body (Key 1). The ball seals must be removed prior to removing the valve ball and valve shafts.

The follower shaft to ball connection uses a follower shaft pin (Key 14) in a stepped hole and can only be installed and removed in one direction. (See Figure 7)

For 3 through 12 inch valves the valve shaft / valve ball connection is made using a shaft key (Key 18), see Figure 9. The shaft / ball connection is factory set, but if the shaft or key needs to be replaced or if the connection is loose it will need to be reset. Refer to the Assembly instructions.

Always use caution and protect the fl ange gasket surfaces from damage during disassembly.

For 1. 1-1/2, and 2 Inch Valves

1 Mark the shaft to show the orientation of the ball before beginning disassembly, this will help to re-install the shaft properly on reassembly. It is possible to install the valve shaft 180 degrees out of alignment which will make it diffi cult to mount the actuator.

2 Rotate the ball to the ‘open’ position and locate the smaller of the pin holes on the ball (see Figure 7). To keep the ball and shaft in proper position it may be necessary to support the ball using a wood or soft block during disassembly. Using a 3/16” pin punch, drive the shaft pin (Key 15) out of the ball / drive shaft (Key 2) connection by driving the shaft pin out the larger side of the pin hole.

3 Using the same 3/16” pin punch, remove the follower shaft pin (Key 14) from the valve ball / follower shaft (Key 13) connection.

4 Remove the pipe plug (Key 28) if present and drive the follower shaft into the ball towards the drive shaft. If the drive shaft cannot be pulled out by hand, continue to drive the follower shaft into the drive shaft until it loosens. Being careful not to allow the ball to drop, pull the drive shaft from the valve body through the actuator mounting end of the valve.

5 Remove and inspect the valve ball for damage. Inspect the valve shafts and valve body for damage as well.

For 3 through 12 Inch Valves

1 Mark the shaft to show the orientation of the ball before beginning disassembly, this will help to re-install the shaft properly on reassembly. It is possible to install the valve shaft 180 degrees out of alignment which will make it diffi cult to mount the actuator.

2 Rotate the ball to the ‘open’ position and locate the smaller end of the keyhole on the valve ball / drive shaft (Key 16) connection. To keep the ball and shaft in proper position it may be necessary to support the ball using a wood or soft block during disassembly.

Ball / Shaft and Bearing Removal (Continued)

For 3 through 12 Inch Valves (Continued)

3 Using an appropriately sized pin punch, drive the shaft key (Key 18) out of the ball / drive shaft connection by driving through the smaller of the keyholes pushing the key away. See Figure 9.

4 Using the a 3/16” pin punch, remove the follower shaft pin (Key 14) from the valve ball / follower shaft (Key 13) connection. Be sure to check the ball / follower shaft connection for a stepped hole, always drive the follower shaft pin from the smaller hole out the larger.

5 Remove the pipe plug (Key 28) and drive the follower shaft inward towards the drive shaft. If the drive shaft cannot be pulled out by hand, continue to drive the follower shaft into the drive shaft until it loosens. Be very careful not to allow the ball to drop especially with larger valves! Pull the drive shaft from the valve body through the actuator mounting end of the valve.

6 Remove and inspect the valve ball for damage. Inspect the valve shafts and valve body for damage as well.

Bearing RemovalNOTE If the bearings (Key 20) need to be replaced, please note that Dyna-Flo bearing confi gurations have changed for 570 series control valves and new replacement bearing kits will refl ect this change.

Inboard and outboard bearings are only present for valve sizes 6” through 12” with S17400 bearing material. All other bearing combinations and sizes utilize two identical bearings.

Thrust washers (Key 19) are only required for valves sizes 6” through 12” with S17400 bearing material. All other bearing combinations and sizes no longer require a thrust washer.

1 Inspect the bearings, remove the bearings only if they are damaged and require removal.

2 Remove the bearings by hand. If the bearings are unable to be removed by hand refer to Table 12 for bearing removal tool dimensions and instructions. CAUTION: If the bearings require removal special tooling may be required. In most cases the bearings can be removed with a standard punch, a standard punch may also damage the bearings.

3 Remove and replace the thrust washer (Key 19) if required.

4 Inspect internal surfaces for evidence of wear and repair if required.

ASSEMBLYEnsure that all parts have been thoroughly cleaned and inspected as per disassembly section prior to assembly. Replace damaged parts and always replace packing and gaskets.

Bearing Assembly

NOTE If the bearings (Key 20) need to be replaced, please note that Dyna-Flo bearing confi gurations have changed for 570 series control valves and new replacement bearing kits will refl ect this change.

Valve sizes 6, 8, 10, and 12 inch use specifi c inboard and outboard bearings. Pay close attention when ordering parts and assembling these sizes. All other sizes use identical inboard /outboard bearings.

Thrust washers (Key 19) are only required for valves sizes 6” through 12” with S17400 bearing material. All other bearing combinations and sizes no longer require a thrust washer.

1 See Figure 11 to determine placement of inboard and outboard bearings if they are used. Install the bearings appropriately by hand or by using the appropriate bearing tool as indicated in Table 13. The fl ange of the bearing should be in contact with the valve body.



P-570M1217B 13


ASSEMBLY (Continued)

Ball / Shaft Assembly

CAUTION To avoid dropping and damaging the valve ball (Key 3) when inserting the ball into the valve body (Key 1) it may be necessary to support the ball using a wood or soft block during assembly.

NOTE For 3 through 12 inch valves the valve shaft / valve ball connection is made using a fl at key (Key 18) and set screws (Key 17), see Figure 9. The shaft / ball connection is factory set, but if the shaft or key needs to be replaced or if the connection is loose it will need to be reset prior to assembly. See Page 27.

1 For valve sizes 3 through 12, set the drive shaft to ball connection prior to assembly. Refer to Page 27 for instructions to set the shaft / ball connection.

2 Carefully insert the valve ball into the valve body. Insert the follower shaft (Key 13) through the valve body and into the valve ball.

3 Align the pin hole of the follower shaft with the follower shaft pin hole on the valve ball. Insert the follower shaft pin (Key 14) into the ball / follower shaft assembly.

4 Install the drive shaft (Key 16) through the bearing and into the valve ball. Set the valve shaft to the original orientation as per Step 1 of Ball / Shaft and Bearing Removal. Install the shaft key (Key 18) or shaft pin (Key 15) for 1”, 1-1/2”, 2” valves, and refer to Pages 25, 26, and 27 for shaft pin and shaft key installation instructions.

5 With the follower shaft pins and fl at key installed beneath the hole on the surface of the ball ear, stake the pins and/or fl at key on both the drive shaft and follower shaft using a center punch. See Pages 25 - 27 for further instructions.

Packing Installation 1 Ensure all parts have been cleaned and inspected prior to replacing the packing. Refer to the Disassembly section for inspection procedures. For Live Loaded packing refer to the Live Loaded Packing instruction manual for rotary valves (P-LLPR).

NOTE To prevent trapping air when installing packing rings it is recommended that packing rings be installed one at a time. Do not force packing rings below the chamfer of the packing bore before adding another ring. See Figure 4.

2 Install the packing parts as shown in Figure 15. For PTFE packing, lubricate the packing with a silicone- based lubricant.

3 Install the packing follower (Key 23).

4 Thread the packing nuts (Key 27) onto the packing studs (Key 26) and tighten them in an alternating pattern until the packing follower is secured. The packing nuts should be tightened enough to stop leakage under operating conditions.

Ball Seal Assembly 1 Have all parts and seal surfaces cleaned and inspected prior to assembly. Refer to Disassembly section for inspection procedures.

2 Rotate the ball (Key 3) to the closed position. Inspect the position of the ball along the axis of the shaft (Key 16). The ball should be no more than 0.005 inches (0.13 mm) off the center line. It may be necessary to use a feeler gauge between the clearance angles just below where the ball seal sits, using a feeler gage the maximum difference would be 0.010 inches (0.254 mm). For 1, 1-1/2, & 2 inch valves the back-up ring (Key 4) will need to be installed to check the position of the ball. If the ball is not centered it may be due to some wear on the ears of the ball or the thrust face of the bearings, re-inspect all surfaces for damage.

For PTFE Composition Ball Seals

A Install the ball seal (Key 5), gasket (Key 9) and seal protector ring (Key 10).

B Install the seal protector clips (Key 11/11A) and seal protector ring screws (Key 12/12A), tighten them completely in an alternating pattern.

For Metal Ball Seals

A Lubricate the radial seal (Key 7) with white petroleum grease and install it into the groove in the seal protector ring (Key 10).

B Install the wave spring (Key 8) into the seal protector ring.

C Insert the metal seal (Key 6) into the seal protector ring, take extra care not to damage the radial seal when inserting the metal seal. Try to keep the metal seal ring from binding as you insert it by keeping it even and parallel.

D Install the gasket (Key 9), then install the metal seal / protector ring assembly over the gasket.

E Install the seal protector clips (Key 11) or washer (Key 11A) and seal protector ring screws (Key 12) or washer screws (Key 12A), tighten them completely in an alternating pattern.

ACTUATOR MOUNTINGRefer to the appropriate actuator instruction manual for additional mounting instructions. For mounting and fail position orientations see Figures 5 & 6.

1 Set the valve to the desired fail position.

2 Clean the splines of the drive shaft and using the marks made in Step 2 of Valve / Actuator Disassembly insert the drive shaft (Key 16) into the actuator lever.

3 Adjust the position of the valve, lever, and actuator so that the lever is centered and the actuator shaft is vertically parallel within the actuator housing. The lever should be able to move within the housing freely and unobstructed. Tighten the lever clamp to the drive shaft.

4 Insert the actuator mounting bolt (Key 30) and bolt the valve and actuator together using the actuator mounting nuts (Key 31). Once the mounting bolts are tight, the valve may need to be readjusted in order to center the valve ball. Refer to the appropriate actuator instruction manual for information on adjusting the actuator turnbuckle to re-center the ball.

5 Re-install the actuator cover plate and travel indicator arrow.

DRIVE SHAFT PIN1 to 2 inch 570’s uses a 1/4” diameter shaft pin (Key 15)(3/16” diameter for 1” 570’s) to connect the drive shaft to the ball that is precisely fi tted to easily insert into the ball/shaft by hand or with light tapping by a hammer and punch. New ball/shaft assemblies will have the pins inserted loose for easy removal prior to installing into the valve. Use a 1/8 pin punch to remove the pin.

CAUTION Because the drive shaft pin hole is stepped, the pin can only be removed from one direction. Once the new Ball, Shaft and Pin is installed, the pin hole must be staked to prevent the pin from coming out during operation. Because the pin can only be inserted from one direction, staking the side that the pin is inserted from will prevent the pin from falling out.

NOTE

Deforming the edges of the hole without properly supporting the ball could result in damage. It is advisable to install the follower shaft into the valve and to carefully support the ball before staking the edge of the hole on the drive shaft to prevent damage from occurring to the ball / shaft assembly. See next page for Follower Shaft Pin assembly.

NOTE 1, 1-1/2, and 2 inch 570 ball/shaft is sold only as an assembled matched set and must be replaced as an assembly.

Figure 18 Use a pointed center punch to stake the edge of the hole as illustrated to the left. In the illustration to the left a shop rag is used to hold the ball in the proper position for staking. Be careful not to damage the machined surfaces of the ball or body.

Staked Pin Photo andFollower Shaft Pin Instructions

available on .

NOTE The ball to shaft connection is set prior to assembly. For instructions on removal of the ball, shaft and key refer to Page 11.



P-570M1217B 27


FOLLOWER SHAFT PIN1, 1-1/2, and 2 inch 570’s follower shaft (Key 13) also uses a straight pin to retain the follower shaft in position. Early designs used a non-stepped 3/16” (1/8” for 1” 570’s) diameter hole in the ball and a longer (1-1/4”) pin which is deformed to allow the pin to tighten in the hole. Later designs use stepped pin hole similar to the drive end. When using a longer (1-1/4” long) pin, you must assure the pin is deformed to allow the pin to tighten in the hole when installed. When using the shorter (1-1/16” long) pin, the pin hole must be staked, as illustrated below, to prevent the pin from coming out during use. Install the follower shaft. For non-stepped holes you will need to stake both sides. Stake the fi rst side, then insert the pin, then stake the second side. For stepped holes insert the pin and stake the large side only.

3 THROUGHT 12 INCH BALL TO SHAFT ASSEMBLY INSTRUCTIONSThese instructions outline the recommended procedure for assembly and setting of the ball to shaft connection. Use these instructions when setting or re-setting the ball to shaft connection or when replacing either the ball or shaft. The ball to shaft connection is set prior to assembly. For instructions on removal of the ball, shaft and key refer to Page 11. The connection design allows for adjustment of a shaft key using setscrews. As the set screws are adjusted clockwise the shaft key is forced against a taper which allows for easy fi eld rotation play in the ball to shaft connection, and when set properly allows for easy fi eld removal.

Using protective covers on the vise jaws to protect against damage to the shaft. Place the shaft in a vise with fl at facing up as shown.

Slide the ball onto the shaft and insert the flat key (flat down) into place. Note the side the shaft key goes in from as shown above.

Rotate the ball and shaft as shownand tighten the setscrews until allrotational play is removed. Do notover tighten or removal wil bediffi cult.

Using the pin punch remove the shaft key.
