The pneumatic
actuators are designed for the transmission of high
torques on the output shaft.
This actuator consists of a mechanical kinematism that transforms
the linear thrust of a single/double acting piston in a torque
on the output shaft of the valve.
Pneumatic actuators can be coupled to every type of valve
having an angular stroke of 90 deg.
Features:
- Double acting version
- Single acting spring return version
- Rack and pinion version
- Scotch-yoke version
- Valve coupling according to ISO 5211
All series of actuator can be equipped with a manual emergency
device as:
- handwheel for manual operation
- hydraulic cylinder with manual oil pump, tank and relevant
equipment
Optional equipment:
- limit switches (open/closed positions)
- solenoid valve
- position transmitter
- positioner and I/P converter
- position transmitter
- air tank for emergency operation
and any other devices.
