Manual ventilation butterfly valve is normally used in pipeline system of ventilation and environment protection of building material, glass, mining, generating plant, light industry, paper-making etc.
Structure features
Manual ventilation butterfly valve is welded by quality carbon steel. It is characterized by reasonable structure, abrasion resistance, small flow resistance, nimble operation, clear direction indication, convenient maintenance and long using life. It may be installed in vertical or in horizontal. Matched with worm wheel driving device, it can be opened and closed freely. You can also adjust the opening freely. It is an ideal equipment to adjust the flow.
