Pneumatic linear actuators

Pneumatic linear actuators are used to actuate control valves in industrial plants. They deliver high actuating forces with short actuating times.
The required reset force is generated by the pressure spring on the diaphragm disc. If the control medium stops, then the spring load returns the actuator to the starting position.
Spring operation
The actuator is optionally available with the spring force extending or retracting the actuator stem.
Highest lifecycle and reliability through the use of roll diaphragms, special seal-wiper combination elements and maintenance-free slide bearings.
