A one-piece body design incorporates fully supported flanged bolt holes to prevent stressing of the mating pipe flanges.
PBFV Thermoplastic butterfly valves feature a blowout-proof stainless steel stem and a unique, 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.
Plastic construction gives this valve corrosion resistance, and the PBFV Thermoplastic butterfly valves will not contaminate sensitive fluids that come into contact with them.
PBFV Thermoplastic butterfly valves come in both PVC and CPVC, featuring either EPDM or FPM liner/seal, and are available in the following sizes: 2˝, 3˝, 4˝ 6˝, 8˝ and 10˝, with 8˝ and 10˝ models also available with a gear operated valve.
PBFV Thermoplastic butterfly valves are available from Dwyer Instruments.
