Asahi/America Introduces Type-57P Butterfly Valves

Type 57P gear and lever

Asahi/America, Inc., the leader in thermoplastic fluid flow technologies, announces the 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 as all 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.

Asahi/America’s 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.

Asahi/America’s Type-57P is assembled to customer specification and tested in our Lawrence, MA facility. Available accessories include stem extensions, chain operators, manual limit switches, 2” square operating nuts, and Asahi/America’s Speed Handle™ for the Plasgear™ operator.

The Type-57P is ideal for water and wastewater treatment, landfills, aquariums, chemical processing, swimming pools and water features, power plants, and mining applications.
