The air-operated back pressure valve adjusts back pressure by controlling the compressed air pressure, controlling the upstream fluid pressure. Pressure can be set anywhere within the adjusting range, continuous control, achieving continuous, stepless back pressure regulation, supports remote, pneumatic and other control modes, Upstream back pressure is controlled by air pressure, may be equal, or varied at a set ratio, air control ratio 1: 1 to 1:100. Air-operated back pressure valves suit applications requiring remote and precise pressure control.
