1 GENERAL

1.1 Scope of instructionsThese instructions contain the most important userinformation related to the actuators in the Metso ECseries. You can obtain further information about valves,positioners and other accessories from the installation,maintenance and operating instructions of each spe-cific model.

1.2 Actuator construction and functionEC series actuators are double diaphragm actuatorsfor control and on-off duty. The actuator is pneumaticand is double acting.

The basic principle of the actuator is a floating centricdiaphragm cylinder construction, where a rolling dia-phragm turns the valve shaft via a backlash-free geartransmission. No cylinder O-rings exist.

Because of the central floating diaphragm cylinderconstruction, the internal forces, which affect andimpose friction on the actuator, have been eliminated.In addition, the structure guarantees backlash-freeaction as well as exceptionally low internal friction.

The mounting interface of the EC actuator conforms tostandard ISO 5211. The mounting interface of theMetso B1C cylinder actuator conforms to the samestandard, which makes the EC actuator and the B1Ccylinder actuator interchangeable.

A positioner is attached directly onto the actuator,which makes external tubing unnecessary. The actuatoralso has a mounting interface which conforms to theVDI/VDE 3845 standard, and which allows connectionof other accessories, such as positioners and limitswitches, to the actuator. External air tubing may beneeded.

If the actuator is used without a positioner, an additionaldirect mounting interface for a solenoid valve, accordingto the VDI/VDE 3845 standard, is provided on the side ofthe actuator. In such cases no external tubing is required.

The rotation angle of the drive shaft can be adjustedwith stroke adjustment screws which are located ateach end of the actuator.

1.3 Actuator markingsAttached to the actuator is a identification label (Fig. 2)with the following information

1.5 Recycling and disposalMost actuator parts can be recycled if sorted accord-ing to material. Most parts have material marking. Amaterial list is supplied with the actuator. In addition,separate recycling and disposal instructions are availa-ble from the manufacturer. An actuator can also bereturned to the manufacturer for recycling and disposalagainst a fee.

1.6 Safety measures

2 TRANSPORTING, RECEPTION AND STORAGE

Check that neither the actuator nor its accessories havebeen damaged during transport. Store the actuatorcarefully prior to installation, preferably indoors in a dryplace. Do not take it to the installation site or remove theend caps until immediately before the installation.

If the actuator diaphragms are separately stored, stor-age should be carried out according to general rulescovering the storage of rubber products. The equip-ment should be stored in a dry place at room tempera-ture, protected from UV radiation. The diaphragms arepacked in a non-transparent plastic bag which shouldnot be opened unnecessarily.

Lift the actuator as shown in Figure 4: In the horizontalposition by sufficiently long hexagon screws whichreplace the adjustment screws, in the vertical positionby an eyebolt which replaces the adjustment screw.

Check the weights from the table in Section 9.1.

3 INSTALLATION AND DISMANTLING

3.1 Operating fluidDouble diaphragm actuators use dry compressed airor natural gas. Oil spray is not required. Actuatorsequipped with positioners use clean, dry and oil-freecompressed air. The air connections are shown in Sec-tion 9.1. The maximum supply pressure for the actuatoris specified on the ID-label (Fig. 2). See also Section1.4.

3.2 Attaching the actuator to a valveThe actuator is attached to a valve via an ISO 5211standard mounting interface. The actuator shaft isadapted to the valve shaft with a separate bushing. Thebushing (II + II) is a two-piece cone-shaped bushing,which is tightened firmly with a tightening screw (I)around the valve shaft.

The bushing and the tightening screw are inserted toactuator drive shaft according to Fig. 5. Cylindrical pins(III) are inserted in the bushing slots, and these must bedirected into the corresponding slots in the actuator dur-ing tightening. Before the installation of the bushing andthe tightening screw, impurities such as old threadlock-ing material have to be removed from the threads of the

WARNING:Do not exceed specifications!Exceeding specifications which are marked on theactuator label may cause damage to the device and,in extreme cases, lead to uncontrolled depressuriza-tion. The consequences are damage to the equip-ment and possible injuries to people.

WARNING:Do not dismantle a pressurized actuator!Dismantling of a pressurized actuator results inuncontrolled depressurization. Do not remove theadjustment screws at the ends of the actuator whilethe cylinders are pressurized. Always close thesupply pressure and depressurize the cylindersbefore dismantling the actuator. Failure to conformmay lead to injuries and damage to the device.

WARNING:The cutting action of the valve!No hands, other bodyparts, tools or other objectsmust be placed in the flow bore of the valve while it isopen. Foreign objects must be prevented from ente-ring the pipe system. During operation the valve actslike a cutter. Close and detach the air supply to theactuator during maintenance. Failure to conform maylead to injuries and damage to the device.

WARNING:Consider the weights of the actuator and the valvecombination during handling!The valve combination must not be lifted only by theactuator, the positioner, the limit switch or the asso-ciated tubing. Attach the lifting belts according toSection 2 when lifting the valve combination. Theweights of the actuators are listed in the tables in Sec-tion 9.1. Dropping the equipment may result in injuriesand equipment damage.

tightening screw, and Loctite 225 or similar threadlockhave to be carefully applied to the threads, as shown inFig. 5. The tightening screw can be turned from insidethe actuator shaft using a suitable hex key, Fig. 6. .

Prior to installation, the correct keyway position of thevalve has to be checked. The bushing has four keyways,two of which are intended for valves with DIN key andtwo for valve shafts with ANSI key. The DIN keyway islocated in the split between the bushing halves , and theANSI keyway is located in the middle of the half bushing.Fig. 7 shows the keyway position when the actuator is ina closed position.

The open or closed positions of the actuator can beidentified either by using compressed air, see Fig. 8, orby checking the position of the pointer at the end of thedrive shaft. The actuator is closed if the direction of theslot in the coupling plate is transverse to the direction ofthe actuator's main line.

The actuator is either mounted directly on the valve, or isattached to the valve bracket with four screws. The tight-ening screw of the bushing should be loosened beforemounting, to allow the shaft to fit easily into the actuator.

The actuator construction allows axial movement of thedrive shaft to compensate the valve shaft movementdue to e.g. thermal expansion. Check, before the screwis tightened, that the drive shaft is in the upper positionof its axial movement, which is its normal position (themounting position shown in Fig. 6). Checking is impor-tant, as the actuator shaft drops down slightly when thescrew is tightened.

The drive shaft axial movement can be observed andmeasured before attachment to a valve. The actuatordrive shaft is in the upper position when its upper sur-face conforms to Table 1 (see Fig. 6).

The drive shaft will automatically find its correct positionif the installation tool H061906 (see Fig. 6) is used. Theinstallation tool is attached instead of the coupling plateusing M4 screws with the drive shaft in lower position(before the valve is installed). Tighten the nut of the toolin such a way that the tool pulls the drive shaft to theuppermost position. The position may be checked fromthe side of the tool.

Install the actuator on the valve and attach the valvemounting screws loosely by hand. Then tighten thetightening screw (I) according to Table 1. The requiredtorque is also marked on a plate close to the drive shafton the actuator housing. The installation tool is

removed, and the coupling plate is reattached. Finally,tighten the valve mounting screws.

Check the axial position of the drive shaft. The shaftposition may not be at the upper or lower position Xgiven in Table 1, or close to those values. Remount theactuator if the position is not correct.

The valve may malfunction if the tightening of theconnection has been carried out improperly.

Finally, the extreme rotation positions of the valve areadjusted with the adjustment screws at the ends of theactuator. The location of the screws for adjusting theclose and open positions of the valve are marked onthe actuator housing (see Fig. 8).

3.3 Attaching accessories to the actuator (model ECU_)

Any positioner, limit switch or other accessory whichsupports the VDI/VDE 3845 connection standard canbe attached to the actuator. In such cases the corre-sponding bracket is used, as well as air tubing, if nec-essary.

The actuator also has a VDI/VDE 3845 standard mount-ing interface for solenoid valves. No tubing is requiredbetween the valve and the actuator if a compatiblesolenoid valve is used.

A separate adapter is used to implement the mountinginterface for the EC05 actuator (see Fig. 10).

3.4 Detaching the actuator from the valveThe actuator is detached in the same way that it isattached, but the order is reversed. First, the positioner,or any other accessory, is detached from the actuator,and the coupling plate is detached from the drive shaft.Next, the bushing is loosened by turning the tighteningscrew counter-clockwise. The tightening screw alsoacts as an extractor. It is highly recommended to use asuitable bushing from the tool set H061544 betweenthe tightening screw (I) and drive shaft. The bushingdimensions are given in Table 2. The actuator canfinally be detached from the valve after the screws thatattach the actuator to the valve have been removed.

The actuator must always be depressurized, and the airsupply tubing detached, before the actuator isremoved.

The respective positions of the actuator and thevalve, and the valve shaft key and the correspond-ing keyway must be considered before they aredetached. This makes reinstallation easier.

4 MAINTENANCE

4.1 GeneralActuators do not require regular maintenance undernormal conditions. Here are some maintenance meas-ures that the end user can carry out, if necessary. Theitem numbers in the text refer to the exploded view andthe part list in Section 8, unless stated otherwise.

4.2 Exchange of diaphragmsExchange of rolling diaphragms does not require theactuator to be removed from the valve. Also, the posi-tioner can remain attached during the exchange.

A diaphragm is exchanged in the following way:

❑ Make sure that the actuator is depressurized.❑ If you remove both ends simultaneously, mark

their positions in relation to the actuator housing.The markings will help you re-install the ends,without the need for re-adjusting the stop screws.

❑ Remove the end screws (22), the cylinder endcap (2) and the O-rings (20).

❑ Remove the end screw (25) of the gear rod (4).This releases the following parts: the gasket washer(26), the diaphragm support plate (6), the rollingdiaphragm (7), and the diaphragm retainer (5).

The diaphragms are supplied as produced (see Fig. 13,Stage 1). The fabric support is situated on the outside ofthe diaphragm cup. The rougher fabric side is placedagainst the diaphragm retainer, which makes the follow-ing pre-treatment of the diaphragm necessary:

❑ Initially, turn the diaphragm (7) inside out (thefabric side will now rest against the diaphragmretainer), then turn the diaphragm edge oncemore (see Fig. 13).

❑ Check and clean the diaphragm retainer (5) andthe diaphragm support plate (6) to remove parti-cles before the diaphragm is installed.

❑ Place the prepared diaphragm on the dia-phragm retainer (5) as shown in Fig. 13, andplace the support plate (6) on the diaphragm.

❑ Place the diaphragm retainer-rolling diaphragm-diaphragm support plate-combination on theend of the piston (4), and fix the items with thescrew (25) and the gasket washer (26). Thescrew (25) is tightened according to the torquedata given in Table 3. Secure the screw using, forexample, Loctite 243 screw lock or similar.

❑ Next, the cylinder end cap (2) is attached.Check, prior to installation, the diaphragm sealgroove in the cylinder end, and remove looseparticles. Lubricate the groove with UnisilikonGLK112 or Molykote III lubricant or similar.

❑ If both cylinder ends were removed, re-installthem based on the markings that were madeduring dismantling.

❑ The cylinder end has two air connections with O-rings. Place the O-rings (20) in the air connec-tions at the end of the actuator housing, and putthe cylinder end carefully in its position againstthe actuator housing.

❑ The seal ring on the edge of the rolling dia-phragm (7) must fit properly into the groove inthe cylinder end, Fig. 14.

❑ The easiest way to attach the end cap is to initiallyplace the rolling diaphragm seal ring half-way intothe groove in the end cap, and slide the cap slightly

sideways. The seal ring will then stretch slightly andslide easily into the groove, as the end is simultane-ously pressed against the housing (1).

❑ Initially, place the end cap in the right position,and avoid turning it once the seal on the rollingdiaphragm is in the groove.

❑ Fix the cylinder end with the hexagon screws (22),once it is in the right position. Tighten the screwsaccording to the torque values given in Table 2.

4.3 Detaching and attaching the drive shaft

The following procedure is used for detaching andattaching the drive shaft:

❑ Detach the actuator from the valve and the posi-tioner or any other accessory from the actuator.

❑ Remove the cross rec head screws (27) and thecoupling plate (15) from the drive shaft (3).

❑ Make a note of the drive shaft (3) position beforedetachment. This can be done by moving theactuator against an end limit, for example byusing compressed air, and by marking the driveshaft position in relation to the actuator housing(1). Marking can be done using a marker or paintdots. Remove from the housing (1) the drive shaft(3) and the guidance ring (16) which has beenattached by a press fit, by using a suitable tool,such as a hydraulic press, see Fig. 15.

❑ Exchange the O-rings (35, 36) of the needlebearings. During exchange it is important to addlubricant (Exxon Unirex S2 or similar) to O-ringsand needle bearings.

❑ Next, reattach the drive shaft (3) to the housing.Lubricate the teeths of the drive shaft well beforereassembling (Unirex S2 or similar). Add plentyof lubricant to the shoulders in the coupling plateside of the drive shaft (EC10, 12, 14). It is impor-tant to observe the correct position when attach-ing the drive shaft. Reassembling is easier whenusing markings applied during the dismantlingstage. If markings have not been made, proceedas follows: The drive shaft has a punched markwhich must be in the position shown in Figure 16.It points towards the threaded hole in the mount-ing interface when the actuator gear rod (4) is inthe middle of its movement range. The gear rodposition can be determined in the following way:Remove the limit screws (23) and the hexagonnuts (24) from the actuator ends. Measure,through the limit screw holes in both ends of theactuator, for example with a calliper, the positionof the piston (dimension X in Fig. 16). The gearrod is in the middle of the actuator when X is thesame from both ends.

❑ Push the drive shaft (3) into position using a suit-able press. When you have made sure the driveshaft is correctly installed, lock it in position withthe guidance ring (16), which is pushed intoposition with a suitable press.

❑ Next, attach the coupling plate (15) with crossrec head screws (27) to the actuator shaft (3).Use screw lock.

NOTE:It is crucial for the function of the rolling diaphragmthat no twist tension remains in the diaphragm.

WARNING:Do not dismantle a pressurized actuator!
