Pneumatic Vacuum Butterfly Valve
Summary:
GIQ vacuum butterfly valve refers to the working pressure is lower than the standard atmospheric pressure, forming a vacuum valve, which is used in the vacuum system to adjust the gas flow, cut and connect the pipeline components. Generally , it used to control the air and non-corrosive gas. Pneumatic vacuum butterfly valve plate adopts clamping structure, that is to say, the sealing ring of the valve plate is clamped, and the leakage is zero. It can be used in low pressure as well as vacuum. The pneumatic vacuum butterfly valve takes the compressed air as the power. The management management butterfly plate rotates to make the opening and closing movement, thus achieves to the pipeline airflow on or off, divides into the double action and the single action. The single action has the spring reset function, may automatically reset in the fault.

Features:
1. The bearing adopts self-lubricating bearing with low friction resistance.
2. Replace the disc sealing ring without removing the valve from the pipeline.
3. The valve can cut off the medium in both directions to achieve reliable sealing and non- leakage in both directions.
4. The shaft seal adopts the special structure of automatic compensation to cut off the connection between the external atmosphere and the pipeline, so as to ensure the vacuum degree of the pipeline.
