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)
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.
