Vacuum Manual Butterfly Valve

The suitable working medium is air and non-corrosive gas.
It is mainly composed of valve body, butterfly plate, valve shaft, sealing ring, transmission device and so on.
The valve shaft is driven by a manual operating device to make the butterfly plate rotate in the range of 90 ° relative to the valve body, in order to achieve the opening and closing and flow control purposes.
The valve can cut off the medium in both directions, to achieve reliable sealing, two-way zero leakage. Self-lubricating bearing, low friction resistance.
The shaft seal adopts a special structure with automatic compensation to cut off the communication between the outside atmosphere and the pipeline, thus ensuring the vacuum degree of the pipeline. The butterfly plate seal can be replaced without removing the valve from the line. The butterfly plate of the valve is mounted in the diameter direction of the pipe. The disc-shaped disc rotates about the axis at an angle of 0 ° -90 ° in the cylindrical channel of the body. When the valve rotates to 90 degrees, it is fully open.
