Advantages:

1. The floating valve seat can automatically find the best sealing position of valve plate in order to reach the better seahng effect and reduce the moment of torsion.
2. The used single-eccentric structure can reduce the abrasion of valve seat in the course of opening and closing and prolong the useful life.
3. The global sealing surface can ensure the valve is sealed and doesn't leak, while closing, even if the valve doesn't fully close.
4. The unique design of pin can ensure the tight junction of the valve plate with the valve stem and it can be replaced.
5. The finish of heat-spraying epoxy resin monolithic coating can effectively preventfrom rusting. It can be suitable for the different medium, only after you replace the material of the sealed valve seat.
6. The well-chosen material ensures the high reliability of every accessory.

Purpose:

This valve adopts the unique principle of "floating airproof'. It can avoid the inner leak and reduce the friction resistance of the sealed valve seat and the moment of torsion. It is widely used for cut-off and regulation in the systems of water supply, sewage treatment and neutral liquids in the mining industry, enterprises and high buildings.
