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.
● Provides a pressure differential on both sides of the back pressure valve piping
● Prevents siphoning, Eliminates dosing variations caused by pressure fluctuations at the injection point
● Used together with pulse dampers to reduce water-hammer damage to the system
● Protects piping, elbows and fittings, reduces the impact of pressure fluctuations
● Delivers its full effect only when used with other line components such as pulse dampers
● Can be controlled remotely, can be controlled by computer, PLC control
● Sensitive operation, high precision
