Valworx 555232A air actuated low emission 2-piece 150# flanged stainless steel ball valves for on-off control of oil & gas, water, air and other media compatible with the materials of construction. Dual-certified fire-safe/low emission valve made of 316 stainless steel mounts between standard ANSI 150 pound pipe flanges. Spring return actuators use an air pressure signal (80-120 PSI) to open and springs to 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.
