The valve adopts symmetrical shaft and flange connection structure, which is good for neutral, and can be used at the end of pipeline. It has simple structure, excellent performance, wide use, convenient disassembly and assembly. The rubber is vulcanized in the inner wall of the valve body, and there is no leakage at the contact with the inner wall of the valve body. The rubber lining is firm, which avoids the movement and redundancy during assembly, and has high reliability and durability.
