IMPORTANT: Check your air supply before installing this valve. Air-Actuated valves requireclean, filtered air to operate properly.

Commonly used air compressors can pickup moisture/humidity in the air, dirt, and oil used in thecompressor itself, and pass them along throughout your system, if not filtered properly. While somenewer air compressors are oil-free, many commonly used are not. In the past few years, compressormanufacturers have switched from standard petroleum based lubricating oils to SYNTHETIC OILS, asthey are thought to make the compressor run more efficiently, and can be changed less often.

However, SYNTHETIC OILS, which can get into the air supply, can cause damage to valve bodiesand solenoids, as well as other processing equipment, by affecting the elastomers and/or plastics thatcome in contact with the air supply.

Special "coalescing" filter regulators and solenoid guards are commercially available to help avert thispotential problem, and remove oils and other damaging elements from the air downstream from the aircompressor. One source that we are aware of is Wilkerson Corp. of Englewood, Colorado (telephone303-761-7601). These filters and other components can be installed downline from the compressor,as well as on control panels, to help minimize the problem, by further cleaning the air before it gets toyour valves and system components. Filter elements should be changed at least once a year, as partof your normal plant maintenance program.

IMPORTANT: Use only C-137 Thread Lubricant and OCP-VI Seal Lubricant on Tri-Clover®

actuators.

These lubricants have been formulated especially to ensure trouble free assembly of Tri-Clover®

actuators. C137 is a non-USDA rated lubricant that helps to prevent thread galling. OCP-VI is USDAH2 rated and is an excellent lubricant for the piston.

How to UseBefore reassembly of any Tri-Clover® actuator, i.e. 761, 361, 161, etc., apply a thin bead of C137lubricant on the lower threads of the cylinder. Lightly coat the O.D. of the piston packing and felt ringwith OCP-VI. On actuators with valve positioners, place a light bead of C137 on the lower threads ofthe positioner housing.

THE C137 LUBRICANT IS NOT INTENDED FOR USE ON ACTUATOR PISTON SEALS, STEMTHREADS, OR ANY OTHER UNSPECIFIED USE.

Tri-Clover now offers OCP-VI in 1/4 and 8 ounce tubes and C137 in 1 ounce tubes. For further

information refer to your Tri-Clover® Actuator Service Bulletin, or contact your Tri-Clover distributor.

INTRODUCTIONThis section covers servicing of the following actuators: Type 10L- 10S (normally open), Type 20L - 20S (Normally Closed) Longand Short, and Type 30L - 30S (Air Both Ways).

The 10 and 20 actuators are identical; with spring returnoperation. The change in description is for describing the modeof operation when coupled to a valve. “10” defines normally openand “20” defines normally closed operation, but physically theyare the same. Type 30 is a double acting actuator that is identicalto the 10/20 except it does not contain a spring. These actuatorswill require minimum maintenance over many years of service.

INSTALLATIONConnect air supply to the 1/8-27 FNPT port(s) located on the green end cap or yoke. Airsupply specifications: 60 to 80 psig for spring return (Type 10 & 20); 35 psig for double acting(Type 30). Refer to table at right if additional product holding pressure is required onnormally closed Type 20 actuators.

Bushing/Packing Replacement

Bushings guide the actuator stem while packings provide sealing around the stem. Thebushing and packing should both be replaced if one or the other fails. Even if only one endfails both ends of the actuator should be serviced. Disconnect and remove actuatorcompletely from valve before proceeding with the steps that follow, see Valve Disassembly.

MAINTENANCE

TYPE 10, 20, AND 30 ACTUATORS

Air pressure measured in psig.*Additional air pressure required to holdagainst 10 psig product pressure.

IMPORTANT:Additional air supply must be relieved whenproduct pressure is not present. Failure to doso will result in pressure damage to the seat.

When using additional air loading it shouldexceed the minimum required by no more than3 to 5 psig.

To prevent personal injury, do not attemptto cut the actuator open. The actuatorspring is compressed and under load.

2. Apply 60 psig air to end cap. The packing and bushing will be forcedout of their counter bores, which will result in an air leak.

3. Remove air supply once the bushing and packing are forced out.

4. Remove end cap, bushing, and packing from the actuator and repeat atother end of actuator.

5. Place red indicator cap over the actuator stem threads.

6. Wipe stem clean. Lubricate new packings with Tri-Clover C137lubricant.

7. Slide new packing over the red indicator cap/stem with the "v" side facing the actuator.Partially insert packing into smallest counter bore using a flat tool to assist the outer lip.DO NOT DAMAGE OR ROLL THE PACKING LIP DURING INSTALLATION.

8. Remove the red indicator cap. Place bushing on top of the packing. Push on the bushinguntil outer flange is flush with the actuator.

9. Repeat to the other end of the actuator.

ACTUATOR STEM NYLON LOCK REPLACEMENTThe Nylon Locking Pin located in the middle of the stem thread keeps the valve stem frombecoming loose due to vibrations. After every disassembly, the nylon locking pin must bereplaced. Punch out the old nylon pin with an 1/8 inch or smaller diameter punch. Insert anew nylon locking pin.

ACTUATOR LUBRICATIONFor optimum performance, lubricate once annually. Inject OCP-V1 into the unthreaded thruhole in each end of the actuator. Roll actuator on a flat surface repeatedly to obtain uniformcoverage of lubricant. Do not over lubricate. This is not a remedy for actuator failure.

1. Remove end cap from actuator. Separate clear stem protectorfrom the end cap. Fasten the end cap without stem protector toone end of the actuator.

Air

CAUTIONTo prevent personal injury, keep hands and tools out ofand away from valve bodies and stems when applying orreleasing air to an actuator. The actuator stem assemblymoves with extreme force and suddenness.

MAINTENANCE

CAUTIONTo prevent personal injury, do not attempt to remove thebushing or packing without the endcap fastened to theactuator. The packing and bushing will be forced out ofthe actuator under air pressure and will be trapped by theend cap.
