Air Actuated Stainless Flanged Ball Valves - Scotch Yoke
Valworx 5552/5553 series air actuated ANSI 150lb. stainless flanged ball valve for On/Off control of water, air, oil and other compatible media. Spring return air actuators (series 5552) require a pneumatic pilot signal to change the valve position, springs will return the valve to the normal failsafe position. Double acting air actuators (series 5553) 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.
Rugged, hard-anodized aluminum construction. Explosion-proof rated to ATEX EX h IIC TX Gb/ EX h IIIC TX Db. 150# ANSI construction, low emission / fire safe / pipeline API approved. 1" to 4".
