Pneumatic Valve Actuators
from GF Piping Systems

All GF Piping Systems 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... [See More]
