Pneumaticdiaphragmactuator
GENERAL
This Series provides high performance, high power diaphragm actuators of multi-spring type that are compact and light. Receiving pneumatic or electric signals, the unit balances the force createdwhen diaphragm is airpressuredthrough positioner and the force of compressed spring, so that the output shaft is controlled and placed at a set position. Control of position by pneumatic signals(20～100KPa) directly applied on diaphragm is also possible.

Performance
Hysteresis：Less than 0.8% of Full stroke with positioner.
