BUTTERFLY VALVES

Series PBFV thermoplastic butterfly valves, for chemical and wastewater applications, incorporates fully supported flanged bolt holes to prevent stressing of the mating pipe flanges. They have a blowout-proof stainless steel stem and a full body liner that has a V-notch retention design. This assures positive sealing of the liner to the valve body. An integrally molded face seal provides positive sealing against the mating flange without the need for additional gaskets. Valves come in both PVC and CPVC, featuring EPDM or FPM liner/seal, and are available in 2 in., 3 in., 4 in., 6 in., 8 in. and 10 in. sizes.
