Hayward Flow Control Systems, a division of Hayward Industrial Products, now offers a new line of butterfly valves designed to replace metal valves in a variety of industrial piping systems. Designed for long-term performance and flexibility, BYB Series Industrial Butterfly Valves feature a one-piece plastic body that can stand up to high flow rates and elevated stress conditions. Lever operated BYB valves are available in 2in to 8in PVC, CPVC, PPL, and PVDF bodies with CPVC, PPL, and PVDF discs. The 14in to 24in sizes are available in the same body and disc materials and feature a high torque gear box. Options include gear boxes on the smaller sizes, stainless steel lugs on all sizes, and electric or pneumatic actuation. A choice of FPM, Nitrile or EPDM full face liners eliminates the need for flange gaskets, and a Type 410 SS stem is completely isolated from the process stream. Type 316 SS stems are available.
