The actuator is suitable for coarse - fine adjustment typically
for batching operation processes.
The repeatability is 100% since stopping is by mechanical stoppers.
It is suitable for application calling for precise fine coarse adjustment
like liquid filling system.
The actuator can be switched to one position from any position very
easily with the solenoid control.
The 3rd position is achieved by the mechanical stopping of the
piston movement in the return stroke by pneumatic stopper pistons.
The Intermediate position is present at 20% opening. The opening
can be adjusted as required by the set screw. This is field adjustable.
The actuator as standard works in reverse action as opposed
to conventional configuration i.e. piston inward stroke opens the
valve & piston outward stroke closes the valve.
The end stops (+/- 10°) are provided on the closing & opening side
of the actuators for setting valve closing precisely.
The springs can be provided to bring actuator to mid position
as a standard (optional attachment).
