SPRING-RETURN ACTUATOR

1. IMPORTANT:

When less than the standard number of springs are used in each

end cap, these springs should be positioned according to the air

supply figures below.

Size 10–20

70 psi - 8 springs - 4 per end cap. Remove center spring.

60 psi - 8 springs - 4 per end cap. Remove center spring.

50 psi - 6 springs - 3 per end cap. Use three on a diagonal.

40 psi - 4 springs - 2 per end cap. Use two in opposite corners.

The values listed below are for standard and less than the

standard air pressure as required per the ordering code.

NOTE: Maximum Operating Pressure Does Not Change.

Ordering Code 4567( )

Supply Pressure (psi) 40 50 60 70 80

Actuator Size End of Spring Torque (in-lb)

10 35 55 75 75 95

15 65 105 145 145 185

20 125 195 265 265 335

2. If a spring-return actuator is being repaired due to a failed spring,

REPLACE all the springs in this actuator, as well as any other

parts which may have been damaged.

3. When replacing the springs in a spring-return actuator, place the

springs in the end cap pocket after thoroughly lubricating each

spring. Be generous with lubricant!

4. With the springs pointing up and the end cap on a solid surface,

place the actuator body over the springs and the proper end cap.

(Each end cap can only be mounted to just one end of the

actuator body, as there is a “fool proof” pin in the end cap which

aligns with a hole in the body.)

5. Force the body down and begin by engaging two end cap screws

(5C) by hand through the end cap. Take each end cap screw up in

SMALL and EQUAL turns. Once the end cap is temporarily

secured to the body, turn the actuator over to its normal position

and uniformly take up the four end cap screws. Uniformly load all

the springs to prevent any spring from buckling.

6. In a similar manner, as in the previous steps, replace the springs

in the other end of the actuator body.
