Valworx 579704 high performance stainless steel butterfly valve for control of air, oil and other media in corrosive environments. Wafer style valve sandwich mounts between customer supplied ANSI /ASME Class 150 and other international standard flanges and gaskets. 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.
The valve is direct mounted to the actuator using the international standard ISO5211 mounting pad.
