The pilot back pressure valve controls main-valve upstream pressure by adjusting the regulator outlet 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 the regulator outlet pressure, may be equal, or varied at a set ratio, air control ratio 1: 1 to 1:100. Pilot-operated back pressure valves suit applications requiring remote and precise pressure control.
