Back Pressure Valves From Neptune Chemical Pump Company Inc
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.
Back Pressure Valves are 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.
