Butterfly Valve for Commercial Applications
Asahi/America, Inc., the leader in thermoplastic fluid flow technologies, introduces the Type-57AT butterfly valve for commercial applications. The Type-57AT meets the pressure and temperature guidelines in ASTM F2389 for up to 12” and integrates seamlessly into Asahi/America’s Asahitec™ PP-RCT piping systems for plumbing and HVAC applications.

The Type-57AT’s polypropylene 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. It is available in both wafer and lugged styles.

Asahi/America’s Type-57AT butterfly valve is available in sizes 1-1/2” through 8” with a green lever, and in 1-1/2” through 14” with our Plasgear™ operator. The Type-57AT top flange features an ISO 5211 F07 – F14 bolt circle, and all sizes can be electrically or pneumatically actuated.

Asahitec™ includes both molded socket fusion fittings (20mm – 125mm) and molded butt fusion fittings (160mm – 315mm), and molded large diameter fittings up to 630mm. Asahitec™ is NSF 14-pw certified for potable water applications, and features lead-free brass adapter fittings.

Asahitec™ is complemented by Asahi/America’s extensive welding equipment fleet and valve product line. Ideal Asahitec™ applications include potable water, HVAC, food and beverage grade water, and water distribution. Asahi/America’s Type-57AT is assembled to customer specification and tested in our Lawrence, MA facility.
