Function
All GF Piping Systems rotary actuators can be used as open/close or control actuators. The double-acting design means that the
valve is opened or closed by the actuator applying compressed air. Depending on the requirement, the springs can open or close.
The single-acting actuators only apply compressed air on one side, while adjustment on the other side is by spring force. This
means that if there is air failure they return automatically to a safety position. Standard interfaces enable easy configuration of:
solenoid valve, limit switch and positioner.
