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.
The Revolutionary and patent-pending BYV Series Butterfly Valve from Hayward features the most advanced thermoplastic design and construction in the industry today.

The revolutionary hand lever design features a 72 spline interlock mechanism allowing for 19 stopping positions every 5 degrees. Additionally, the hand lever material incorporates a UV-inhibitor for enhanced performance in outdoor applications. The BYV features reinforced lug holes and can be ordered with overmolded 316 stainless steel lugs for dead end service. Designed for global use, the BYV is available in ANSI and DIN/EN flange patterns with a pressure rating of 150 PSI @ 70°F across all sizes and materials.
