The proportional solenoid back pressure valve adjusts back pressure according to the control signal, controlling the upstream fluid pressure. Pressure can be set anywhere within the adjusting range, continuous control, achieving continuous, stepless back pressure regulation, supports remote, program, computer and PLC control, for applications requiring remote and precise pressure control, an electro-pneumatic proportional back pressure valve is recommended.
