Back Pressure Valves

What is a Back Pressure Valve?
Back Pressure Valves maintain a set pressure at the pump outlet port (discharge) to assure accurate metering and are also used to prevent syphoning. Use of the Back Pressure Valve assures proper metering pump check valve operation when the system pressure against which the pump is injecting fluid is too low.

The Back Pressure Valve is a required accessory when pumping to a low pressure injection point below the tank level or when pumping from a bulk tank with a high head pressure. They are ideal for use on high pressure treatment.

What are the benefits of a Back Pressure Valve?
They are made of a broad range of valve body materials with a long life teflon diaphragm. They are field adjustable to a maximum back pressure of 50 psi and are low maintenance.
