Pneumatic 3 Pieces Flange Ball Valve for on-off control of water, air, oil and other compatible media. Spring return actuators require a pneumatic pilot signal to change the valve position, springs will return the valve to the normal failsafe position.

Double acting actuators use air pressure to open the valve and air pressure to close the valve. Advantages of air actuated ball valves over other type valves may include: higher flow rates, higher pressures, higher temperatures, wider media compatibility, straight through flow path, reduced water hammer, and use in hazardous environments.
