Cast Steel Worm Gear Triple Eccentric Wafer Butterfly Valve

Description

The Cast Steel Worm Gear Drive Triple Eccentric Hard Seal Wafer Butterfly Valve is a metal-seated, triple-offset butterfly valve in a compact wafer body, operated by a worm gearbox. The triple offset ensures the multi-layer seal ring touches the seat only at final closure, giving friction-free movement and tight shut-off at high temperature. The wafer pattern saves weight and installation length compared with flanged versions.
