Designfunksjoner:
The U-shaped flange 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.
U-shaped flange butterfly valves are widely used in coal chemical, petrochemical, rubber, paper, pharmaceutical and other pipelines as media splitting, confluence or flow switching devices.
