The PQ340FH manual turbine side mounted eccentric half ball valve utilizes an eccentric valve body, eccentric sphere, and valve seat. When the valve stem rotates, it automatically centers on a common trajectory, and during the closing process, it becomes tighter and tighter, fully achieving good sealing performance. The ball and valve seat of the valve are completely detached, eliminating the wear of the sealing ring and overcoming the problem of constant wear between the traditional ball valve seat and the sealing surface of the ball. Non metallic elastic materials are embedded in the metal seat, and the metal surface of the valve seat is well protected. This product is particularly suitable for media such as steel, aluminum, fibers, small solid particles, pulp, coal ash, petroleum gas etc.
Product features:
- The internal valve seat is a movable valve seat, which has a certain wear compensation effect and is easy to replace and disassemble.
- It has a wide range of applications and can be used for various ordinary pipeline media.
- The valve body is integrally cast, with fewer connection points, resulting in fewer leakage points.
