Standards:

U type flange end butterfly valve has reliable performance, compact structure, flange connection, easy installation, 90° opening and closing, worm gear drive, small operating torque, two-way sealing, excellent performance, superior parts processing performance, flow characteristics tend to be linear, and good adjustment performance and sealing There are many auxiliary materials to choose from, allowing users to choose valves that can be used as vent valves at the pipe end with reliable performance. The butterfly valve flange end  body is lined with a removable soft rubber sleeve; the butterfly flange  valve body is lined with a removable rubber sleeve with a skeleton; a layer of rubber is pasted on the surface of the valve body. In addition, in order to improve corrosion resistance, the butterfly plate is also lined with rubber material, and its material is determined according to the corrosiveness of the medium. The connection form of this kind of valve is mostly clamping type, and the butterfly plate is mostly center plate type. In order to reduce friction, it is also made into double eccentric type. If the flange end butterfly valve body, butterfly plate and other inner cavities are all lined with rubber, it is called a fully rubber-lined flange end butterfly valve. Because it uses a "U"-shaped sealing ring, it must be a centerline type, so it is also called: U-shaped centerline butterfly valve flange end .
