Double Eccentric Butterfly Valve

BOVE Double Eccentric Butterfly Valve adopts an resilient pressure self-sealing valve seat and metal seal structure, which has bi-direction zero leakage and can achieve lower torque and reduce the purchase cost of the drive unit. The cam-effect sealing structure separates the valve seat from the valve disc after opening the valve at a certain angle, which reduces friction and greatly improves the service life of the valve. It is widely used in the interception and adjustment of various pipeline fluids. Multiple solutions.
