Air actuated soft seated butterfly valve for on-off control of hydrocarbons, oil and other media compatible with the materials of construction. Lug style valve sandwich mounts between standard ANSI /ASME B16.5 Class 125 / 150 flanges. Double acting air actuators use air pilot pressure to open the valve and air pilot pressure to close the valve.
