| HA Multi-spring Film Actuator |
|
HA Multi-spring Film Actuator changes output pressure of pneumatic adjusted instrument into displacement of push rod. So long as it is contacted with the body of contr
ol valve, the core would be moved at the position relative to the input signal.
This Multi-spring Film Actuator is compact in structure and big in output.
