This company has added two new sizes (10- and 12-in.) to its Type-57P family of chlorinated polyvinyl chloride (CPVC) butterfly valves (photo). The new models are well suited for facilities where large-diameter CPVC body and disc butterfly valves are needed due to elevated water temperatures. The valves are available with ANSI wafer-style connection or with 316 stainless-steel lug inserts. Additionally, Type-57P CPVC valves can be actuated both electrically and pneumatically, and various manual accessories can be installed. — Asahi/America, Lawrence, Mass.
