Lug Style Butterfly Valves are for valves used at the end-of-line applications, mounted on single flange. Also used as a blocking valve where either side of the valve can be unbolted, while still maintaining system pressure on the opposite side of the valve. 316 stainless steel lug inserts.
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. All models standard with 316SS shaft.
