Butterfly Valves & Actuation

Asahi/America Type 57 Butterfly Valves disc has about the same diameter as the connecting piping, and the flow is straight through, with a low pressure drop. The solid thermoplastic butterfly valves have a lined body design and bubble-tight seal with only the liner and the disc as wetted parts. Asahi/America Type 57 Butterfly Valves are self-gasketing, eliminating the need for additional flange gaskets. Asahi/America Type 57 standard model has a PVC or PP body with a polypro, CPVC or PVDF disc for better chemical and abrasion resistance at temperatures higher than can be achieved with other PVC butterfly valves. All models standard with 316SS shaft.
