    Back Pressure Valve & Pressure Relief Valve

    The Diaphragm Back Pressure Valve is an accessory valve of the metering pump. The back pressure valve can provide the system with a pressure of 0-3bar to meet the minimum working pressure requirements of the metering pump, ensure flow accuracy, and have an anti-siphon function. The valve is simple, reliable, sensitive, and has excellent corrosion resistance.Robust construction ensures reliability in the rigorous service of municipal and industrial applications.

     

    The Diaphragm Pressure Relief Valve is an accessory valve of the metering pump.

The valve is simple, reliable, sensitive, and has excellent corrosion resistance.Robust construction ensures reliability in the rigorous service of municipal and industrial applications.

     

    Metering pump and positive displacement pumps will have excessive delivery when working under low pressure.In order to prevent similar problems, a back pressure of at least 0.7 Bar must be at the inlet and outlet of the metering pump.This can be achieved by installing a back pressure valve in the outlet pipe of the metering pump.
