Asahi/America introduces the Type-57P Butterfly Valve
06 February 2018
Asahi/America, Inc. has announced its next generation Type-57 butterfly valve: the Type-57P. The redesigned valve is available in an ANSI wafer-style connection and shares the same face-to-face dimensions like all the like-size Asahi/America Type-57 butterfly valves.
New features of the Type-57P include two molded tag holes in the valve body for user-defined valve identification, and a highly visible throttle positioning plate. The plate, which features an opening degree legend in 10-degree increments, makes accurate throttle positioning between zero degrees (closed) and 90 degrees (open) possible.
The Type-57P’s body and disc are injection molded for durability, and the 316 stainless steel stem is non-wetted. For high cycle life and smooth torque, the seat and disc bushings have been fitted with dual O-ring seals.
The Type-57P butterfly valve is available in sizes 1-1/2” through 8” with a lever, and in 1-1/2” through 14” with our Plasgear operator. Available body and disc materials include PVC, CPVC, PP and PVDF. The Type-57P top flange features an ISO 5211 F07 – F14 bolt circle, and all sizes can be electrically or pneumatically actuated. Available accessories include stem extensions, chain operators, manual limit switches, 2” square operating nuts and Asahi/America’s Speed Handle for the Plasgear operator.
