Pneumatický pohon PA30 -PA90

The pneumatic actuator series PA30- PA90 serves to operate valves with a 90° positioning angle. Georg Fischer actuators already comply with both the EN standards, as well as divers ISO standards: Actuator mounting flange according to ISO 5211; Actuator connection with square according to DIN 3337; Connection for solenoid valve, positioner and limit switch according to VDI/VDE 3845 (NAMUR); Optical position feedback

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 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.
