A New Twist in Butterfly Valve Design From Hayward Flow Control

The BYV Series Butterfly Valve from Hayward Flow Control incorporates the most advanced thermoplastic design and construction for butterfly valves in the industry today. Available in multiple thermoplastic materials from sizes 2" through 12" / DN50 - 300, the BYV Series has an extremely robust one-piece body construction while lighter weight than metal valves of equal size.

The revolutionary hand lever features a 72 spline interlock mechanism allowing for 19 stopping positions at every 5°. The engineered hand lever material incorporates a UV inhibitor for enhanced performance in outdoor applications. The BYV also features reinforced lug holes and can be ordered with over-moulded 316 stainless steel lugs for dead end service or isolation needs. The BYV Series is available in ANSI150 and DIN/EN PN10 flange patterns, with a pressure rating of 150 PSI / 10 Bar at 70°F non-shock across all sizes and materials.

All BYV Series butterfly valves are backed by Hayward's Exclusive 2 Year Warranty and made by Hayward in Clemmons, NC, USA.
