Valves & Actuation

The Revolutionary and patent-pending BYV Series Butterfly Valve from Hayward features the most advanced thermoplastic design and construction in the industry today. Available in multiple thermoplastic materials from 2" through 12” the BYV has an extremely robust body construction while lighter weight than a metal equivalent. 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.

Twice the Temperature / Pressure Rating
Hayward Swing Check Valves have up to twice the temperature/pressure rating of other plastic swing check valves and can often replace metal valves
in many applications.
Built-In O-Ring Flange Seals
Hayward Swing Check Valves are furnished ready for installation with two built-in o-ring flange seals. There is no need to purchase additional, expensive
flange gaskets.
Self-Aligning Clapper Seal
Bubble-tight checking, with a minimum of only 3 psi back pressure, is assured with Hayward’s rugged, self-aligning clapper seal design.
