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 Process Management 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 disc 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.

1052 Size 20 Actuator (F & G) February 2011 Instruction Manual D100322X012 Proper bench set of the spring can only be made when the actuator ”up” travel stop has been approximately adjusted. Insert a shaft in the actuator and adjust the ”up” travel stop before establishing spring compression (since there is no travel stop in the upper diaphragm casing). Considerable error in adjustment is certain if the above procedure is not followed.
