Pneumatic buttefly valve

Highlight: Pneumatic buttefly valve

Product introduction:

The butterfly disc is installed along the diameter of the pipeline. Inside the cylindrical passage of the butterfly valve body, the

disc-shaped butterfly disc rotates around its axis within an angle range of 0° to 90°. When the rotation angle reaches 90°, the

valve is fully open. This type of valve is generally installed horizontally in pipelines. Soft-sealed center-line wafer butterfly

valves and double-eccentric flanged butterfly valves feature compact structures, easy 90° rotation for switching, reliable

sealing, and long service lives. They are widely used in water supply and drainage systems of waterworks, power plants,

steel mills, paper mills, chemical industries, food industries, etc., for flow regulation and on-off control.

Product features:

This valve adopts a double-eccentric structure, featuring a sealing function that tightens as it closes, ensuring reliable sealing performance.
The sealing pair is composed of stainless steel and nitrile oil-resistant rubber, ensuring a long service life.
The rubber sealing ring can be positioned on either the valve body or the butterfly disc, adapting to media with different characteristics for user selection.
The butterfly disc features a frame structure, offering high strength, a large flow area, and low flow resistance.
The overall baking finish effectively prevents corrosion. By only replacing the sealing seat material, the valve can be applied to different media.
This valve has a bidirectional sealing function, allowing installation in any direction without being restricted by the media flow direction or spatial position.
The valve features a unique structure, flexible operation, labor-saving design, and convenient handling.
