The bi-directional  sealing valve is developed based on the triple eccentirc metal seated butterfly valve .

Benefits
1.Designed with bidirectional sealing structure,the valve can be installed at any sides ; one set valve 's function is the same as two  set of valves ,it reduced the cost .

2.Since the metal sealed butterfly valve is offered with self-sealing device,reliable sealing performance can be realized under the pressure from medium;

3.The really metal seated butterfly valve in the world ,longer life time

4.The unique  semi ball sealing structure  ,as well as the sphere-conical sealing surface of the valve seat,makes for shear force . The solid particle will be crushed when the  bidirectional sealing  butterfy valve is opened .

5.Large size can be fabricated ,the max size is DN3000;
