Back Pressure Control Valves

We have Back Pressure Control Valves for metering pump application dispense to atmospheric conditions or into a process with less than 20 psig pressure and more typically, into a process with erratic system pressure. These uses require Back Pressure to ensure a constant pressure for the discharge check assembly on the metering pump to work properly. It is crucial that Back Pressure Valves be installed in the discharge piping of the pump to ensure a constant pressure for the discharge check assembly to work under. This allows for the repeatability of a constant fluid discharge per stroke, and accuracy desired. Additionally, Back Pressure Valves automatically provide anti-siphon protection.
