Eccentric hemispherical valve Half-ball Valve

Eccentric Semi-ball Valve is a specialized valve designed for handling harsh media containing solids, fibers, or prone to scaling. Its core feature is a geometrically eccentric design: the rotational center of the spherical crown (half-ball) is offset from the centerline of the valve seat. This allows the crown to completely disengage from the seat during opening and closing, minimizing wear. Sealing is achieved through a wedging action at the end of the closing motion.
