Structural features：

        1、This butterfly valve structure size is short, small volume, light weight, convenient operation.
        2、This butterfly valve adopts triple eccentric structure, closed the shut tight with the function, butterfly plate can be two-way confined, sealed performance is excellent, zero leakage, after open ensure surface completely from Seal surface contact, protect Seal is not damaged.
        3、Seat with a body structure, reducing the direct contact with the media valve seat, thus reducing the degree of the valve seat by erosion, extend the life of the valve seat。
        4、Seat made of stainless steel sheet and the graphite sheets stacked together, this structure can effectively prevent the medium and small thermal expansion of solids caused by Seal surface bite. Even if minor damage occurs, it will not leak.
       5、Seal fixed mode adopted bolt oval distribution fixed, not only accurate location, but also make each bolts are balanced force, to eliminate the uneven distribution of stress caused by the seal looseness and leakage.
       6、Can choose a variety of standard pipe flanges and flange sealing surface type, can use manual, worm gear drive, electric, pneumatic, hydraulic drives and other ways to meet the different needs of users.
