Series 79 Pneumatic Actuator Option - Safety Springs

The Safety Spring option for single acting pneumatic actuator allows for the removal of the end caps for maintenance or changing of the fail orientation without the fear of injury due to the stored energy of the springs. We have incorporated a captive spring design (shown as the black, green and yellow items) into the concentric spring pack so that they are contained, and the stored energy remains just that; stored.

The Safety Spring option is available for the C79P through the G79P. The output torque of the actuator and actuator dimensions are unaffected with this option.

Ideal Applications Include:
