Hayward Flow Control 8″ BYV Series Butterfly Valve
The Hayward BYV14080A0EG000 is a heavy-duty, 8-inch thermoplastic butterfly valve engineered for superior flow control in corrosive and demanding environments. Featuring a high-strength PVC body and a Glass Filled Polypropylene (GFPP) disc, this valve is built to handle chemical processing, water treatment, and industrial fluid handling with ease.
This specific unit is equipped with a Gear Operator for effortless manual actuation and features an EPDM liner and seals, providing excellent resistance to weather, heat, and a wide array of chemicals.
Key Performance Features
Hydro-dynamic Centric Disc: Engineered to minimize pressure drop and maximize flow performance, resulting in an impressive Cv Coefficient of 2820.
Full Boot Liner Design: The EPDM liner serves as the primary disc seal and the face seal for mating flanges, eliminating the need for additional flange gaskets.
Non-Wetted 316SS Stem: The one-piece stainless steel stem provides high strength and absolute disc positioning without coming into contact with the process fluid.
Gear Actuation: Provides precision control and mechanical advantage, allowing for smooth operation of the 8″ disc even under pressure.
ISO 5211 Mounting: Features an integral top mounting flange, making it easy to transition from manual gear operation to electric or pneumatic actuation in the future.
