Double Eccentric Butterfly Valve
U type butterfly valve -LWBV-6 is a normal type of butterfly valve.
U-type butterfly valve is widely used in coal chemical, petrochemical, rubber, paper, pharmacy and other pipelines as media splitting, confluence or flow direction switching device.

The U-shaped butterfly valve adopts a top-mounted structure, which reduces the connecting bolts of the valve body under the conditions of high pressure and large diameter, enhances the reliability of the valve and can overcome the influence of the weight of the system on the normal operation of the valve. It is very advantageous in industrial applications. U type butterfly valves are very reliable and require little maintenance.
