The Metal seated butterfly valve adopts a double eccentric structure and a inclined cone seal. The seal-ring can be separated once open the disk, and the valve can be sealed once the seal-ring contacts the disk. This structure can decrease the friction torque when the butterfly valve opens and closes, and expanded the life time, and make opening and closing easily.

斜锥面金属密封蝶阀设计采用了一个双偏心和一个特殊斜锥椭圆密封结构，实现蝶板在开启瞬间密封面即分离，关闭接触即密封的效果，这种密封结构实现启闭无机械滑动摩擦，大大延长了密封件的使用寿命，并且达到启闭轻松自如目的，且具有密封自动补偿功能。
