The revolutionary BYV Series butterfly valve from Hayward® features the most advanced thermoplastic design and construction in the industry today. These valves have an extremely robust body construction while being lighter than a metal equivalent. They are an excellent option for water and wastewater treatment plants, aquatic and animal life support systems, chemical processing and handling, marine and corrosive environments, mining, metal plating and surface finishing, landfills and environmental infrastructure, and water parks and theme parks. The BYV series features reinforced lug holes and can be special ordered with overmolded 316 stainless steel lugs for dead-end service needs. More materials (glass-filled polypropylene body/disc or nitrile liner) and 10" and 12" sizes are also available by special order, contact us for a quote.
