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