The Series PBFV Thermoplastic Butterfly Valves are an economical thermoplastic
constructed butterf ly valve ideal for chemical and wastewater applications. A one-piece
body design incorporates fully supported flanged bolt holes to prevent stressing of the
mating pipe flanges. Series PBFV valves feature a blowout-proof SS stem and a unique,
full body liner that has a V-notch retention design that 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. Plastic construction gives this valve
superior corrosion resistance and the valves will not contaminate sensitive fluids that come
into contact with them.
