Cast Steel Manual Triple Eccentric Hard Seal Wafer Butterfly Valve

Description

The Cast Steel Manual Triple Eccentric Hard Seal Wafer Butterfly Valve is a lever- or handwheel-operated, metal-seated wafer butterfly valve. Its triple-offset sealing geometry delivers friction-free opening and closing with tight metal-to-metal shut-off, while the compact wafer body installs easily between flanges. It is an economical high-performance valve for smaller, frequently operated high-temperature lines.
