Double Acting Actuators:

A.  Back off one travel stop screw, leaving it partially 

threaded in the end cap. Entirely remove the other 

stop screw from the other end cap.

B.  Open valve using air pressure. NOTE:  Actuator will 

leak due to removed travel stop.

C.  Use the indicator pointer on top of actuator to 

determine if valve is open to desired position. If not, 

repeat steps 1-3, backing off or screwing in stop 

screw to attain proper open position of valve.

D.  Make sure O-ring is in proper position in countersunk 

area on end cap and the washer is in place. Tighten 

down nut to set stop position.

E.  Thread in the other travel stop, making sure the 

O-ring and washer are in the correct place. When the 

travel stop will not thread any further, tighten nut to 

set stop position.

F.  The previous steps set the open travel stop. See 

section 4.3.5 for instructions on setting the close 

position stop.

Spring Return Actuators:

A.  Back off one travel stop screw, leaving it partially 

threaded in the end cap. Entirely remove the other 

stop screw from the other end cap.

B.   Open valve using air pressure. Note actuator will leak 

due to removed travel stop.

C.  Keeping air pressure applied to actuator, use the 

indicator pointer on top of actuator to determine if 

valve is open to desired position. If not, remove air 

pressure and repeat steps 1-3, backing off or screwing 

in stop screw to attain proper open position of valve.

D.  Make sure O-ring is in proper position in countersunk 

area on end cap and the washer is in place. Tighten 

down nut to set stop position.

E.  Thread in the other travel stop, making sure the 

Oring and washer are in the correct place. When the 

travel stop will not thread any further, tighten nut to 

set stop position.

F.  The previous steps set the open travel stop. See 

section 4.3.5 for instructions on setting the close 

position stop.
