Valworx 555312A air actuated ANSI 150# stainless steel flanged ball valves are designed for general chemical and industrial applications. Full port 2-piece designed investment cast valve direct mounts to the actuator with standard ISO5211 mounting pad. Dual-certified fire-safe/low emission valve made of 316 stainless steel mounts between standard ANSI 150 pound pipe flanges. Double acting actuators use an air pressure signal (80-120 PSI) to open and close the valve.. The valve will fail closed upon loss of air signal. High temperature valve mounting kit available for extended temperature range or wall mounting applications. Ball valve can be mounted in any orientation. All valves are tested per API 598.
