Electric Metal Seal Triple Eccentric Butterfly Valve Carbon Steel Stainless Steel

Electric metal seal triple eccentric carbon steel stainless steel butterfly valve adopts three eccentric structure design, the eccentric distance between the valve seat and the valve body, the eccentric distance between the valve shaft and the valve seat, the eccentric distance between the valve shaft and the valve body are not equal, this structure can effectively reduce the friction of the valve, improve the service life of the valve and control accuracy.
