Introduction

Scope of Manual

This instruction manual provides information on installa-

tion, adjustment, maintenance and parts ordering for the

Type GA 1.21, GA 1.31 and GA 1.41 actuators.

Description

The direct acting (extends stem) actuator (figure 6 and 9)

W6681b

and the reverse acting (retracts stem) actuators (figure 7

and 10) are spring-opposed pneumatic diaphragm actua-

tors that provide throttling or on-off operation of sliding-

stem control valves. The Type 3024S ATC actuator

springs are located under the diaphragm plate, and they

fully retract the actuator stem for fail action upon loss of

diaphragm casing pressure. The Type 3024S ATO actua-

tor springs are located on top of the diaphragm plate, and

they fully extend the actuator stem upon loss of diaphragm

casing pressure.

Only personnel qualified through training or experience

should install, operate and maintain Type 3024S actua-

tors.
