Introduction
Scope of Manual
This instruction manual provides information on
installation, 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 actuators 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
actuator 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 actuators.
