Valworx 535216 2-piece 150# flanged stainless steel ball valves with stainless steel rack & pinion actuator 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. All-stainless construction for superior corrosion resistance.
The valve is direct mounted to the actuator using the international standard ISO5211 mounting pad.
High temperature valve mounting kit available for extended temperature range or wall mounting applications.
