All actuators are factory lubricated for life, butstill should be protected from the elements and storedindoors until ready for use. The ports of the actuator areplugged as supplied from the factory. If actuators arestored for a long period of time prior to installation, theunits should be stroked every 3 months to prevent theseals from taking set.2. Prior to assembly, manually open and close valveto insure freeness of operation. Be sure valve and actuatorrotate in the same direction and are in the same position(i.e., valve closed, actuator closed).Heavy Duty ActuatorInstallation InstructionsField Conversion from Fail CW to Fail CCW(For Spring Return Actuators)1. Apply supply air to actuator and loosen Stop Bolt JamNut (17) and back off clockwise Stop Bolt (16) to removeall spring cartridge preload.2. Remove supply air from actuator.3. Support Spring Cartridge (11) and loosen all 4 Nuts(41) evenly till all 4 nuts are loose. The spring cartridgedoes not have to be removed.3. Check the mounting surfaces, the stem adaptor and thebracket to assure proper fit. Secure the valve in the closedposition with the stem vertical. Bolt the bracket to the valveand place the stem adaptor on the valve stem. Position theactuator over the valve and lower to engage the stemadaptor to the actuator shaft. Continue to lower until theactuator seats on the bracket mounting surface. In order toalign the bolt holes, it may be necessary to turn or strokethe actuator a few degrees and/or adjust the actuator travelstops. Bolt the actuator to the bracket.4. After consulting the valve manufacturer's recommendations,adjust the travel stop bolts of the actuator forthe proper open and closed valve positions. Pneumaticallystroke the actuator several times to assure properoperation without binding of stem adaptor. If the actuatoris equipped with an Ultraswitch or other accessories adjustthem at this time.5. To prolong actuator life use only clean, dry plant air.Lubricated air is not required, however it is recommendedparticularly for high cycle applications. Caution: Do not uselubricated air with positioners.Travel Stop AdjustmentsAll actuated valving requires accurate travel-stop adjustmentsat both ends of the stroke to obtain optimumperformance and valve seat life. The accumulation oftolerances in the adaption of actuators to valves is suchthat there must be a range of adjustments for both endsof the stroke to achieve the expected performance. TheHeavy Duty series actuators have travel stop adjustmentsin both the clockwise and counter-clockwise directions.The 12 degree overtravel feature provides adjustmentsfrom -6 to +96 degrees.4. Remove the Position Indicator (44) or any otheraccessories that may be on the output shaft.5. Remove the Bearing Retainer Screws (14) from thevalve mounting side and slide the Retainer Plate (13) offthe shaft.6. The Torque Shaft (20) may now be tapped out using asoft faced hammer. Use care not to drop the shaft or theBearing (12) when they come out.7. Rotate Torque Shaft (20) end for end and reinstallinto the Yoke (4) using care to line up the shaft with theBearing (12) on the opposite end. Push the shaft thru tillthe shaft bottoms out. This should only require handpressure to reinstall the shaft.8. Reinstall the Bearing (12) back into the housing until itis flush with the top of the housing.9. Reinstall the Bearing Retainer Plate (13) and Screws(14) insuring that the Gasket (37) is in place.10. Tighten the Spring Cartridge Nuts (41) evenly untilthey are all 4 evenly tightened. See bolt torque chart.11. Apply supply air to actuator and reset Stop Bolt (16).Never try to adjust stop bolt against force of spring.12. Reinstall any accessories or position indicator onTorque Shaft (20).13. Check actuator for proper operation.14. The result of this operation is that the “valve”side of the actuator has been reversed.A00032-1 GU (AUTO-9) 5/01 Page 1 of 4© 2001, Flowserve Corporation, Provo, UT
