Butterfly ValvesVideo
Butterfly valves of Weidouli are widely used in chemical industry, petrochemical industry, marine development, smelting, etc., as regulating and closing equipment.
The seat and disc of our butterfly valve employ the most advanced technology to complete the structural design. At the very moment when the disc opens and closes, the disc produces a cam action, which can pull the disc with less effort, greatly reduces the wear and deformation of the valve seat, and increases the service life of the valve.
