Flange Connection Double Eccentric Plug Valve

Eccentric semi ball valve is designed on the base of O type ball valve, which solves the difficulties of conveyance of ''solid-liquid" and "solid-gas" two phase medium.

Features

Straight-through valve body :In full open state, the rectilinear flow of fluid makes for less energy loss than other valves.

Convenient operation: The valve disc will be separated from the valve seat when the E-ball valve is opened. The starting torque is small and turning of the eccentric half ball valve with worm wheel is flexible.

Double eccentric structure: With the utilization of the eccentric-locked cam mechanism, closing of the double eccentric half ball valve is tight and reliable with outstanding sealing performance.
Wedge clamping force: When closing the eccentric half ball valve, dirt and the adhesion on the sealing surface can be removed, which is conducive to the avoidance of scale formation.

The material of sealing surface is hard alloy,so the valves have anti-flushing function.
