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, which play a role in cutting off fluid and regulating medium flow.
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, which play a role in cutting off fluid and regulating medium flow.
Features:
1. This butterfly valve design structure is novel, the overall size is small and lightweight.
2. The butterfly plate adopts a 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.
