1. . Actuator is suitable for coarse – fine adjustment, typically forbatching operations or processes.

2. The Actuator has to be Double Acting.

3. The repeatability is 100% since stopping is by mechanicalstoppers. It is suitable for application calling for the precise fine-coarse adjustment like liquid filling system.

4. The Actuator can be switched to one, position from any otherposition very easily with the solenoid control. The 3rd positionis achieved by the mechanical stopping of the piston movement,in the return stroke by pneumatic stopper pistons.

5. The Intermediate position is present at 20% opening. Theopening can be adjusted as required by the set screw. This is field adjustable.

6. Actuator as a standard, works in reverse action, as opposed toconventional configuration i.e. piston inward stroke opens thevalve, and piston outward stroke closes the valve.

7. The End Stops (+/- 5°) are provided on the closing and openingside of the Actuator for setting valve closing precisely.

8. 5,00,000 Cycles POD.
