Product Description

Double Eccentric Flange Soft Seal Butterfly Valve

Usage and features
    Flange soft seal butterfly valve is suitable for metallurgical, chemical power and municipal engineering and water plant medium for water, oil, and other air pipelines plays a role in cutting off fluid and regulating medium flow.
Features:
1. This butterfly valve design structure is novel, the overall size is small, lightweight.
2. The butterfly plate adopts double eccentric, quick opening and closing, easy operation and labor-saving.
3. The butterfly plate adopts double eccentricity so that there is no sliding friction between the butterfly plate and the sealing ring. The sealing surface has long wear resistance, reliable sealing, and easy adjustment.



Working Principle & Manufacturing Standard

Rotate the butterfly valve handwheel, drive the valve stem butterfly plate to rotate freely in the range of 90 degrees through the worm and worm wheel transmission, and make the butterfly valve in the open or closed state to achieve the purpose of connecting or cutting off the medium.
