Matco-Norca (Brewster, NY) offers a range of rugged B5 and B6 Series butterfly valves for use in industrial applications. B5 Series valves are available in wafer and lug style in 200 PSI 2”–12” and 150 PSI 14” – 36” sizes. The discs are available in ductile iron, aluminum-bronze or 316 Grade stainless steel. Valves with BUNA-N liners are suitable for oil and gas applications; valves with EPDM liners are suitable for high temperature water and air applications up to 250°F. The B5 has a broached disc that is specifically designed to accept the milled square stem, thus providing substantially lower torque values.
