Stainless steel flanged 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, and the spring will return the valve to its normal fail-safe position. Double-acting actuators use air pressure to open the valve and air pressure to close the valve.
