Introduction

The CVS Series 1051/1052 Diaphragm Rotary Actuator is a pneumatic spring-return actuator designed for use with rotary-shaft control valves. This is a direct-acting actuator, and an increase in the loading pressure extends the diaphragm rod out of the spring barrel. The CVS Type 1051/1052 Actuator is suitable for on-off service, or for throttling service when used with a valve positioner. The Series 1052 Actuator includes a spring adjuster, which is suitable for use with or without a positioner.

The stroking time is dependent on the actuator size, rotation, spring rate, initial spring compression and supply pressure. If the stroking time is critical for your application, consult CVS Controls Ltd. for proper settings.

The travel indicator is a combination graduated disk and pointer located on the actuator end of the valve shaft. Fixed travel stops are an available option.

Warning: The sudden release of process fluid can cause personal injury or property damage. Prior to starting adjustment procedures:

• Isolate the valve from the process,

• Release the process pressure, and

• Vent the actuator loading pressure.

Correct turnbuckle adjustment ensures the valve is correctly closed when the actuator is against its travel stops. Refer to Figure 7 for Key Numbers.

For accurate adjustment to the zero-degree valve ball position, remove the valve from the pipeline. Refer to instructions in the appropriate valve body instruction manual.

A regulated air supply will be required to stroke the actuator. Consult Table 4 for the sizes of the three open-end wrenches required for the procedure.

Note: To achieve the most accurate adjustment of the actuator, do not remove the cover during this procedure (Key 41).

1. Remove the access plate (Key 11) and machine screws (Key 29) if included.

2. Loosen the lower locknut (Key 14).

3. Ensure that there are no tools or instruments within the actuator housing and blocking the stroke path. Add pressure to the diaphragm casing to stroke the actuator down and provide access to the left-hand threaded upper locknut (Key 18). Loosen the locknut.

4. Use one of the following according to the service required by the actuator:

a. Push-Down-To-Close: Slowly stroke the

actuator to the down travel stop. Determine the closed position of the valve according to the appropriate valve body manual. Adjust the turnbuckle until the valve is in the closed position and lock this adjustment with the left-hand threaded locknut (Key 18). Stroke the actuator to the mid-travel position and tighten the locknut (Key 16).

b. Push-Down-To-Open: Determine the

closed position of the valve according to the appropriate valve body manual. Release all pressure from the diaphragm casing and ensure that the diaphragm is against its up travel stop. Check the valve position and stroke the actuator so the turnbuckle (Key

16) is accessible through the access opening. Adjust the linkage, release pressure to the actuator and check the new adjustment. Continue this procedure until the valve is in the closed position when the actuator is resting on its up travel stop. Tighten the locknut (Key 14), stroke the actuator and tighten the left-hand threaded locknut (Key 18).

5. Replace the access plate (Key 11).

6. Loosen the self-tapping screws (Key 7), adjust the travel indicator (Key 38) and retighten the self-tapping screws.

Principle of Operation

As the loading pressure is increased on top of the diaphragm the diaphragm rod moves down. As the loading pressure is decreased, the diaphragm rod is forced upward by the spring.

The spring and diaphragm have been selected to fulfill the requirements of the application. When in service the actuator should produce full travel of the valve with the diaphragm pressure as indicated on the nameplate (Figure 2)

For principle of operation of the actuator with a valve positioner, refer to the separate positioner manual.

Maintenance

Actuator parts are subject to wear and tear which requires inspection and replacement as necessary according to the severity of service conditions. The following instructions outline adjustment, disassembly and reassembly of parts. Refer to Figures 7 & 8 for Key Numbers.

Warning: The sudden release of process fluid can cause personal injury or property damage. Prior to starting adjustment procedures:

• Isolate the valve from the process,

• Release the process pressure, and

• Vent the actuator loading pressure.

Disassembly

The CVS Type 1051 Actuator can be completely disassembled by following these procedures. When inspecting or repairing the actuator, perform only those steps necessary. Under normal conditions, the cap screws (Keys 2, 42 and 43) should not be removed.

Note: Cap screw (Key 12) must be disengaged from the lever (Key 33) prior to removing the diaphragm casing (Key 26). Failure to do so will allow the spring compression to rotate the valve beyond its fully open or closed position. This could cause damage to the valve seal.

1. Bypass the control valve, relieve all loading pressure and remove the tubing or piping from the top of the actuator.

2. If the control valve assembly includes a valve positioner, remove it from the assembly.

3. Remove the cap screws and washers (Keys 8 and 9) as well as the cover (Key 41).

(Keys 36 and 30) from the cover.

5. Inspect the bushing (Key 40). If replacement is necessary, remove the travel indicator scale (Key 39) by first unscrewing the self-tapping screws (Key 37).

6. Remove the cap screw and hex nut (Keys 12 and 31).

7. Note the orientation of the lever/valve shaft, and then loosen the cap screw (Key 10).

Note: Avoid using a hammer to drive the lever (Key 33) off of the valve shaft. On some valve types this could cause the valve ball and bearings to move from their centered position, causing damage to valve parts during operation.

If using a tool is necessary, use a wheel puller to remove the lever. Tapping the wheel puller screw lightly to loosen the lever is permissible, but hitting the screw with excessive force could also cause damage to valve parts or disrupt the positioning of the valve ball and bearings.

Warning: Before proceeding further, remove the cap screws and relieve the spring compression. Failure to do so may cause personal injury if the compressed spring force suddenly thrusts the upper diaphragm casing away from the actuator.

8. Loosen but do not remove the casing cap screws (Key 45). Ensure that all spring force in the upper diaphragm casing has been relieved. Unscrew and remove the cap screws and hex nuts (Keys 45 and 44) then remove the upper diaphragm casing and the diaphragm (Key 25).

9. Refer to the warning on the CVS Controls nameplate (Key 27) located on the diaphragm plate (Key 1).

10. Remove the diaphragm plate (Key 1) and the attached parts from the actuator. The following parts will be attached to the diaphragm head: spring (Key 21), diaphragm rod (Key 22), cap screw (Key 24), spring seat (Key 19), hex nut (Key18), turnbuckle (Key 16), hex nut (Key 14) and rod end bearing (Key 13).
