WARNING

To avoid personal injury or property damage, the 1052 size 70 actuator, due to its weight, must be externally supported if mounted in the horizontal position.

3. When mounting the actuators, make sure that the bushing (key 67) and valve shaft are in‐line so that the bushing

will slide onto the valve shaft without damage.

4. Mount the actuator on the valve body and secure it with the valve mounting screws. The torque for 1/2 to 1‐inch

shafts is 88 NSm (65 lbfSft); for 1‐1/4 to 1‐1/2 inch shafts is 136 NSm (100 lbfSft); for 1‐3/4 to 2‐inch shafts is 183 NSm (135 lbfSft).

CAUTION

Exceeding any torque requirement may impair the safe operation of this actuator by causing broken or damaged parts. Refer to table 3 for the bolting torque requirements.

5. Screw the left‐hand threaded locknut (key 58) onto the diaphragm rod (key 10) as far as possible.

6. Screw the turnbuckle (key 57) as far as it will go onto the actuator rod.

7. Screw the locknut (key 16) as far as it will go onto the rod end bearing (key 17). Thread this assembly completely

into the turnbuckle (key 57).

8. If the lever (key 27) is attached to the rod end bearing, remove the cap screw and hex nut (keys 18 and 19).

9. If the 1052 spring adjustment has been changed, complete the Initial Setting portion of the 1052 Spring

Adjustment section before proceeding.

10. Consult the appropriate valve instruction manual's Installation section for lever/valve shaft orientation marks, and

slide the lever into place (see figure 4). Clamp with the cap screw (key 28).

11. Rotate the lever (key 27) to align with the rod end bearing (key 17). This connection can be aided by moving the

actuator off its up travel stop with a regulated air source and adjusting the turnbuckle (key 57) slightly.

12. Apply sealant (key 77) or equivalent thread‐locking compound to the threads of the cap screw (key 18).

13. Connect the lever (key 27) and the rod end bearing (key 17) with the cap screw and hex nut (keys 18 and 19).

Tighten the cap screw to the recommended bolt torque shown in table 3.

14. Note the valve position and direction of rotation. Position the travel indicator (key 37) accordingly.

a. If no handwheel actuator is to be used, position the travel indicator (key 37) according to the valve position just

noted. Replace the cover (key 33), and secure with washers and cap screws (keys 34 and 63). If holes in the cover and housing (key 20) do not align, temporarily loosen the cap screws (key 23), and shift the housing slightly.

CAUTION

To avoid parts damage, do not stroke the actuator while the cover (key 33) is off.

16. Follow the instructions given in the Turnbuckle Adjustment section before proceeding to the Loading Connection

section.

Valve Flow Direction

Valve construction can change the flow direction for a control valve assembly. It is important to observe the flow direction in all valve applications before installing the valve in the pipeline (see figure 3). Refer to the appropriate valve bulletin or instruction manual.

Note

Observe all warnings and cautions provided in the appropriate valve instruction manual Installation section.

Loading Connection

1. Connect the loading pressure piping to the pressure connection in the top of the diaphragm casing. Run either pipe

or tubing between the pressure connection and the instrument. If necessary, remove the 1/4 inch bushing in the pressure connection to increase connection size.

1052 Size 70 Actuators

Instruction Manual

D104083X012

2. Keep the length of pipe or tubing as short as possible to avoid transmission lag in the control signal. If an accessory

(such as a volume booster or a valve positioner) is used, be sure that the accessory is properly connected to the actuator. If a valve positioner is part of the assembly, the pressure connection to the actuator will normally be made at the factory.

3. When the control valve is completely installed and connected to the instrument, check for correct action

(air‐to‐open or air‐to‐close) to match the controlling instrument. For successful operation, the actuator stem and valve shaft must move freely in response to the loading pressure change on the diaphragm.

Adjustment

Turnbuckle Adjustment

Correct turnbuckle adjustment ensures that the valve is correctly closed when the actuator is against its travel stops. Key numbers are shown in figure 8.

For accurate adjustment to the zero‐degree valve disk or ball position, remove the valve from the pipeline. Refer to the valve instruction manual for instructions.

A regulated air supply will be required to stroke the actuator. Refer to table 4 for the sizes of the three open‐end wrenches required for this procedure.

1. Remove the access plate (key 59). Also remove the machine screws (key 60), if present.

Note

For the most accurate adjustment of the actuator, do not remove the cover (key 33) during this procedure.

2. Loosen the lower locknut (key 16).

3. Make sure the actuator housing (key 20) is clear of any tools or other instruments that could obstruct the actuator

stroke path. Pressure the diaphragm casing enough to stroke the actuator down so that the left‐hand threaded upper locknut (key 58) is accessible through the access opening. Loosen the locknut.

4. Consult the appropriate valve instruction manual for determining the closed position of the valve. Then use one of

the following:

a. Push‐down‐to‐close—Slowly stroke the actuator to the down travel stop. Adjust the turnbuckle (key 57) until the

valve is in the closed position. Lock this adjustment with the left‐hand threaded locknut (key 58). Stroke the actuator to the mid‐travel position, and tighten the locknut (key 16).

b. Push‐down‐to‐open—Release all pressure from the diaphragm casing, making sure the diaphragm is against its

up travel stop. Be sure that the optional handwheel is adjusted to its topmost position so that the zero position of the actuator and valve can be reached simultaneously. Check the valve position. Stroke the actuator so the turnbuckle (key 57) 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. Stroke the actuator to the mid‐travel position, and tighten the locknut (key 16). Stroke the actuator, and tighten the left‐hand threaded locknut (key 58).

5. Replace the access plate (key 59).

6. Loosen the self‐tapping screws (key 38), adjust the travel indicator (key 37), and re‐tighten the self‐tapping screws.

1052 Spring Adjustment

Initial Setting

The 1052 nameplate specifies an initial spring setting, which is the initial setting adjusted into the actuator spring. Initial setting is the casing pressure at which the diaphragm and diaphragm rod begin to move away from the up travel stop with the actuator disconnected from the valve. (With the actuator connected to the valve and pressure applied to the valve, a higher pressure will be required to start actuator travel).

The initial setting was selected (based upon the service conditions specified when the actuator was ordered) so that, when the actuator and valve are in service, the valve will seat properly and full travel will be obtained within a diaphragm casing range of 0 to 2.3, 0 to 2.8, or 0 to 3.8 bar (0 to 33, 0 to 40, or 0 to 55 psig) depending on specific actuator size and construction.

If the actuator has been disassembled or if the spring adjustment was changed, and it is desired to match the initial setting stated on the nameplate, make sure the rod end bearing (key 17, figure 8) has been disconnected from the lever (key 27, figure 8). Adjust the spring so that the diaphragm rod just starts to travel at the spring set pressure specified on the nameplate.

Be sure the rod end bearing does not hit the lever as the diaphragm and diaphragm rod move away from the up travel stop. To adjust the spring, insert a round rod into one of the holes in the lower bearing seat (key 73, figure 8). Hole diameter is 19.1 mm (3/4 inch) for size 70 actuators. Rotate the bearing seat to move it toward the casing to increase initial setting or away from the casing to decrease initial setting (keys 1 and 2, figure 8).

Stroking Range

The initial spring setting listed on the nameplate has been determined to be the optimum setting, and it is not recommended to make spring adjustments that will cause this value to change or be exceeded. For push‐down‐to‐open valve action, the initial spring setting is the maximum allowable to provide the maximum spring closing force.

CAUTION

Any increase of this setting will over‐stress the spring at full travel and may shorten the fatigue life of the spring.

For push‐down‐to‐close valve action, the initial spring set has been determined to be the optimum balance between the air‐to‐close and the spring‐to‐open breakout torque.

If the 1052 actuator is to be changed from one valve action to another (i.e., push‐down‐to‐close to push‐down‐to‐open), first, refer to the table for key 11 in the Parts List section to determine the proper initial spring setting; then, adjust the unit according to the procedures in the Initial Settings portion of the 1052 Spring Adjustment section.

Principle of Operation

The diaphragm rod moves down as loading pressure is increased on top of the diaphragm. As the loading pressure is decreased, the spring forces the diaphragm rod upward.
