Valve Actuators

The Series 92 electric actuator is our primary electric actuator for most butterfly valves, and our larger ball valves, as well as multi-turn diaphragm and gate valves.

The Series 94 electric actuator is a basic electric actuator designed for smaller (generally up to 4") quarter-turn valves, and is a good low-cost alternative to larger electric actuators. The Series 94 actuators have a thermally protected, bi-directional, capacitor run motor with a permanently lubricated gear train. Because of their size, the Series 94 actuators have a short open/close time, approximately 5 seconds, and a weight of only 3.5 lbs.

Series 79 PAG pneumatic actuators have a glass reinforced Polyamide housing for chemical resistance and high strength. The actuator functions using a double piston rack and pinion arrangement for a smooth torque profile throughout the actuator stroke. Air to spring models feature a concentric spring set for consistent output torque. The base of the actuator has an ISO output drive and bolt circle for easy mounting to quarter turn valves. The top of the actuator has a visual position indicator and a NAMUR mounting pad to accommodate mounting accessories. The air ports are ¼" NPT and have a NAMUR bolt pattern to accommodate flush mount solenoids.

Our Pneumatic Full Plastic Actuators PA11/21 can serve you in many ways. They are available with or without stroke limiter as well as in the different modes of operation. Accessory assembly to our PA11/21 is easy due to the new position indicator with integrated NAMUR interface. The flange interface also corresponds naturally to the NAMUR standard; therefore, third party valves are no problem.

The Electric Actuators EA21, EA31, EA42 are not only excellently equipped but also can make their point with very high torques; therefore, these actuators can be used to actuate a wide range of valves.

The EA11 is our basic version for the open/close operation of smaller torques. The electric actuator EA11 consists of a gear, a direct current motor, a base print as well as equipment for end stops in its standard version.

The Pneumatic Actuator Series PA30 to PA90 serves to operate valves with a 90o positioning angle. Georg Fischer actuators already comply with both the EN standards, as well as diverse 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.

The Series 94 electric actuator is a basic electric actuator designed for smaller (generally up to 4") quarter-turn valves, and is a good low-cost alternative to larger electric actuators. The Series 94 actuators have a thermally protected, bi-directional, capacitor run motor with a permanently lubricated gear train. Because of their size, the Series 94 actuators have a short open/close time, approximately 5 seconds, and a weight of only 3.5 lbs.
