Valve features - high-pressure butterfly valve

　　■When the valve is open up to 90°, the gap between the valve plate sealing surface and the valve seat sealing surface is much larger than that of single eccentricity.

　　■ These two eccentric structures produce a cam-like effect. When the valve is open, the valve plate can be away from the valve seat withouta large pulling force.

　　■ When the valve plate is removed from the valve seat, the valve plate will no longer contact with the valve seat, which reduces the friction between the valve plate and the valve seat, reduce the torque time required for valve opening and extend the valve life.

　　■ The design of the valve body conforms to ANSI design standard to assure sufficient the safety and strength of the integralcast valve body.

　　■ The core of the three-eccentric metal hard seal butterfly valve is an elliptical cone overlaid with wear-resisting hard alloy on the surface.

　　■ The three-eccentric compound sealing structure has the seat sealing surface formed by valve body overlaid welding and the sealing ring is made of stainless steel and elastic material.

　　■Geometrically,the valve seat and seal ring are used in the whole opening and closing travel of the valve to eliminate wear and leakage.

　　■ The three-eccentric butterfly valve has very low torque and long life due to the friction between the valve seat and the sealing surface of the valve plate is almost zero.

　　■ The unique design of three-eccentricities makes it an ideal hard-sealed valve for high temperature, high pressure, toxic and harmful media
