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

Brand: German WardWODE

Imported pneumatic high vacuum butterfly valves refer to valves that operate at pressures below atmospheric pressure, creating a certain vacuum. These valves are used in vacuum systems to regulate air flow, cut off, and connect pipelines. They are generally used to control air and non-corrosive gases. The valve plate of the pneumatic vacuum butterfly valve is equipped with a clamping structure, which tightly secures the sealing ring, achieving zero leakage. Besides being used in vacuum conditions,,Also operable under low pressure. The pneumatic vacuum butterfly valve is powered by compressed air, rotating the disc plate to control the opening and closing movement, thereby achieving the connection or disconnection of pipeline airflow. It is available in double-acting and single-acting types. The single-acting type features a spring return function, which can automatically reset in case of a fault.

Features of imported pneumatic high vacuum butterfly valves:

 1The bearings feature self-lubricating design, offering minimal friction resistance.

2No need to disassemble the valve from the pipeline to replace the butterfly seat gasket.

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 level of the pipeline.
