Electric Eccentric Half-Ball Valve

The electric eccentric ball valve is a new type of ball valve with a structural design similar to a triple-offset hard-seal butterfly valve. Its closure element is derived from a portion of the ball. During the opening and closing process, the ball no longer contacts the valve seat sealing surface, eliminating friction and sticking. This reduces wear on the sealing components and significantly extends the valve's service life.
