Introduction
Scope of Manual
This instruction manual includes installation, adjustment, operation, maintenance, and parts information for the
1052, size 20, Style F and G diaphragm rotary actuator (figure 1), and the optional top‐mounted handwheel (figure 4).
Instructions for the control valve, rotary positioners, and accessories are included in separate manuals.
Do not install, operate, or maintain a 1052 actuator without being fully trained and qualified in valve, actuator, and
accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is important to
carefully read, understand, and follow all the contents of this manual, including all safety cautions and warnings. If you
have any questions about these instructions, contact your Emerson sales office
before proceeding.
Description
The spring‐and‐diaphragm actuator is used on small rotary shaft valves for throttling or on‐off applications. It mounts
to V150 Vee‐Ball™ valves, V500 valves, eccentric disk valves, and butterfly valves with 3/8 inch and 1/2 inch splined
shafts. The actuator accepts a 3610J, 3620J, or PMV positioner. A top‐mounted handwheel is available for the unit.
Specifications
Specifications are shown in table 1 for 1052 Style F & G size 20 actuators. Some specifications for a given actuator, as it
originally comes from the factory, are shown on the nameplate attached to the actuator.

Operating Principle
Direct Acting: Increasing loading pressure forces the
diaphragm rod from the top to the bottom of the
casing
Stroking Time
Depends on rotation, spring rate, initial spring
compression, and supply pressure. If stroking time is
critical, consult your Emerson Automation Solutions
sales office

(1)
Principle of Operation
Key numbers refer to figure 5. The diaphragm rod (key 10) moves down as loading pressure is increased on top of the
diaphragm (key 3). As the loading pressure is decreased, the spring (key 11) forces the diaphragm rod upward.
The spring and diaphragm are selected to meet the requirements of the application and, in service, the actuator
should produce full travel of the valve with the diaphragm pressure as indicated on the nameplate.
Consult the positioner instruction manual for actuator principle of operation with positioner.
Installation
WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury.
Personal injury or equipment damage caused by sudden release of pressure may result if the valve assembly is installed
where service conditions could exceed the limits given in table 1 or on the appropriate nameplates. To avoid such injury or
damage, provide a relief valve for over‐pressure protection as required by government or accepted industry codes and
good engineering practices.

Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.

CAUTION
To avoid parts damage, do not use an operating pressure that exceeds the Maximum Diaphragm Casing Pressure (table 1)
or produces a torque greater than the Maximum Allowable Valve Shaft Torque (see Catalog 14). Use pressure‐limiting or
pressure‐relieving devices to prevent the diaphragm casing pressure from exceeding its limit.
The actuator, as it comes from the factory, is normally mounted on a valve. Follow valve instructions when installing
the control valve in the pipeline.
A 1/4 NPT pressure connection is located on top of the actuator. Run either 1/4 NPT pipe or 3/8 inch tubing between
the pressure connection and the instrument. Keep the length of tubing or pipe as short as possible to avoid
transmission lag in the control signal. If a valve positioner is used, the pressure connection to the actuator will
normally be made at the factory.
When the control valve is completely installed and connected to the actuator, check it 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.
Use the following steps to connect a valve and an actuator that have been ordered separately. Because the procedures
in the Mounting Procedure section require removal of initial spring compression, it is necessary to read the Spring
Compression Adjustment section before completing the installation.
Mounting Procedure
This procedure assumes that the style ordered from the factory (A, B, C or D) was correct. Key numbers refer to figure
5.
1. Remove the positioner if one is used, and unscrew machine screws (key 40) to remove the positioner bracket or the
cover (key 39).
2. Consult figure 2 for available mounting styles and positions. The actuator is normally mounted vertically with the
valve in a horizontal pipe run.
3. Ensure all the initial spring compression has been removed from the spring. To relieve spring compression, insert a
screwdriver blade between the notches at the base of the spring adjusting screw (key 74) as shown in figure 3. Push
the tip of the screwdriver blade to the right. This rotates the spring adjusting screw counterclockwise. Continue
until the stop is reached which occurs when the spring seat (key 13) is lowered to the adjusting screw base.
4. Before sliding the valve shaft into the lever, position the valve as follows:
D For push‐down‐to‐close action, the valve should be fully open.
D For push‐down‐to‐open action, the valve should be fully closed (see the valve instruction manual).
5. Position the lever in the housing to align with the holes at each end of the housing. Compare the position of the
lever to the position shown in figure 2. Notice that when the lever is in the correct position to receive the valve
shaft, the ”down” travel stop is nearly vertical, as shown in figures 3 and 5.

6. Slide the valve shaft into the lever. Insert the lever in the opening. Tighten the valve mounting cap screws
(see table 2).
7. Remove machine screws (key 36) and remove the hub (key 29) and the travel indicator scale (key 35).
8. Reposition the hub on the splined valve shaft so that the travel indicator screw holes align with the offset portion
(where the rod end bearing connects) of the lever.
9. Loosen the hex nut (key 145) to allow the valve shaft to slide out of the clamped lever (key 27).
10. Center the lever in the opening. For newer clamping levers, torque the cap screw and nut (keys 28 and 145) to a
torque listed in table 2.
11. With the hub positioned properly, the travel scale and indicator can show the correct position of the valve and point
in the direction of flow when the valve is open. Replace the machine screws, fastening the travel indicator scale to
the housing and the travel indicator to the hub.
