PBV Series Back Pressure Valves

All thermoplastic diaphragm Back Pressure Valve for chemical feed systems, applies back pressure to a metering pump to prevent siphoning and eliminates varying dosage rates resulting from fluctuating downstream pressure. All valves are preset for 50 psi, but are field adjustable via the adjustment screw.
