Imported Pneumatic Vacuum Butterfly Valves (Imported Pneumatic Absolute Vacuum Butterfly Valves, Imported Pneumatic Vacuum Valve Brands, Imported Pneumatic Vacuum Butterfly Valve Manufacturers)

Brand: German WOERDWODE

Imported pneumatic high vacuum butterfly valves are valves that operate at pressures below atmospheric pressure, creating a certain vacuum. They are components used in vacuum systems to regulate gas flow, cut off, and connect pipelines, and are generally used to control air and non-corrosive gases. The valve plate of the pneumatic vacuum butterfly valve uses a clamping structure to tightly seal the sealing ring, achieving zero leakage. In addition to being used in vacuum conditions,,It can also be used under low-pressure conditions. The pneumatic vacuum butterfly valve operates using compressed air to rotate the disk plate for opening and closing actions, thereby controlling the flow of air through the pipeline. It is available in double-acting and single-acting versions. The single-acting type features a spring return function, which allows for automatic reset in the event of a fault.

Features of Imported Pneumatic High Vacuum Butterfly Valves:

 1The bearings are self-lubricating, featuring low friction resistance.

2The butterfly plate seal can be replaced without removing the valve from the pipeline.

3The valve can achieve bidirectional cutoff of the medium, ensuring reliable sealing with zero leakage in both directions.

4The shaft seal employs a special structure with automatic compensation, effectively separating the external atmosphere from the pipeline, thereby ensuring the vacuum degree of the pipeline.
