Wafer Soft Seat High-Performance Butterfly Valves are engineered for demanding applications and have proven reliability in extreme service conditions. These valves are ideal for high-temperature services, steam throttling control, polymerizing media, and liquor service with entrained solids. They also excel in high-cycle industrial gas applications, process gas-off handling, paper stock isolation, and vacuum pump isolation. Designed for versatility, they provide exceptional performance in corrosive chemical environments, fire-safe refinery and chemical services, heat transfer systems, and throttling hydrocarbon processes.
