Rubber Lined Butterfly Valve

The butterfly plate of the rubber lined butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis of the valve stem, and the rotation angle is between 0° and 90°. When the rotation reaches 90°, the valve is in a fully open state. Rubber lined butterfly valve should generally be installed horizontally in the pipeline.

The valve body adopts a split type, and the seal at both ends of the valve shaft is controlled by adding fluorine rubber to the rotating base surface between the butterfly plate and the valve seat; to ensure that the valve shaft does not contact the fluid medium in the cavity. At present, rubber lined butterfly valves, as a component used to realize on-off and flow control of pipeline systems, have been used in many fields such as petroleum, chemical industry, metallurgy, and hydropower.
