1" PP Back Pressure Valve 10-50psi w/PTFE/EPDM Diaphragm NPT Ends
Product Description
The Hayward PBV Series Back Pressure Valves enhance the performance of Chemical Feed systems by applying consistent back pressure on metering pumps to produce predictable delivery. The PBV Series also provides an Anti-Siphon function. The PBV Series is available in sizes from 1/4 to 4", with PVC, CPVC, PP and PVDF wetted bodies. The set pressure is factory set at 50 psi but is easily field adjustable between 10 to 150 psi (other pressure ranges are available by request). Backed by Hayward's 3-year warranty, the PBV Series back pressure valves will provide reliable service for your Chemfeed applications.
