Back Pressure and Pressure Relief Valves

Back Pressure valves provide positive back pressure for systems with less than the minimum required pressure difference between the discharge and suction side of the metering pump to assure best metering performance. Select to match the pumps' discharge connection size. In installations where the injection point is lower than the level of chemical in the supply tank the potential for gravity feeding of chemical is a possible concern. Back Pressure valves prevent this from occurring and can be easily added to most chemical feed pumps.
