Top mounted eccentric hemispherical valve

Overview：

The top mounted eccentric hemispherical valve is a valve designed with an eccentric valve body, eccentric sphere, and valve seat. It automatically centers on a common trajectory through the rotation of the valve stem, achieving a tighter and tighter sealing effect as it closes. Its characteristic is that the ball and seat of the valve are completely detached, eliminating the wear problem of the sealing ring, and non-metallic elastic materials are embedded in the metal seat to protect the metal surface of the valve seat. This valve is particularly suitable for media such as steel industry, aluminum industry, fiber, small solid particles, pulp, coal ash, petroleum gas, etc.
