Back,Pressure,Valves,Neptune,Chemical,Pump,Company,IncBack 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.

Relief Valves protect the piping and system from overpressure. Discharge is piped to supply tank.

Back Pressure Valves Features:

  • Broad range of valve body materials

  • Long life Teflon´┐Ż diaphragm

  • Field adjustable to a maximum back pressure of 50 psi

  • Low maintenance
