Values given are for lubricated fasteners.
Minimum values given will provide longer diaphragm cycle life for valves in non-autoclave and low
thermal cycle conditions.
Maximum values given may be necessary for autoclave conditions and for high thermal cycle conditions.
Torques should be applied at near ambient conditions (< 100ºF/ 38ºC).
Actuator operating pressure
Maximum permitted air supply pressure is 90 psig (6.2 bar, 620 kPa).
The actuator has a pressure rating of 90 psig. However, the actuator will withstand pressures well in excess
of the rated pressure without risk of bursting. Maintaining operating pressure at or below 90 psig will
ensure optimum life of the operating components, such as the actuator diaphragm. However, operation at
pressures up to 100 psig (6.9 bar), for limited periods of time, will not noticeably affect the life of these
components.
Set the adjustable opening stop
These instructions are for series 3, 5, 8, 16 actuators.
1. Remove the switch package, if present.
2. Using air pressure and a bleed type regulator, open the valve to the desired position.
3. Rotate the adjusting bushing counterclockwise until resistance is felt. The opening stop is now set.
4. Adjust the valve closed switch.
Set the adjustable opening stop
These instructions are for series 47 actuators.
1. Remove the switch package, if present.
2. Remove the clear plastic cap.
3. Using air pressure and a bleed type regulator, open the valve to desired position.
4. Rotate the adjusting bushing counterclockwise until resistance is felt. Count and record the number of
turns.
5. Loosen the two jam nuts and turn the lower nut clockwise the same number of turns as recorded above.
6. Lock the nuts together.
7. Adjust the travel stop. Follow steps in Adjust the travel (closing) stop.
8. Replace the clear plastic cap.
Set the manual over-ride (close)
For series 47 actuator, fail open and double acting only. Wrench closing not available on series 3, 5, 8, 16,
or 33.
1. Remove the switch package, if present.
