High quality ventilation butterfly valve for Metallurgy

Rectangular pneumatic ventilation butterfly valve is a kind of pneumatic ventilation butterfly valve. The flange port of pneumatic ventilation butterfly valve is square. Generally, the order can be based on the inner diameter.
The rectangular pneumatic ventilation butterfly valve is made of steel plate welding. It has short structure size, light weight, convenient installation, small flow resistance, large circulation, avoiding the influence of high temperature expansion, and light operation. The large expansion between the butterfly plate and the valve body can effectively prevent the jam caused by thermal expansion and contraction. The rectangular pneumatic ventilation butterfly valve is a non-closed butterfly valve, which is widely used in industrial pipelines such as metallurgy, normalization, electric power, building materials, mining, etc., to control or regulate medium gas.
Ten characteristics of rectangular pneumatic ventilation butterfly valve:
1. The rectangular pneumatic ventilating butterfly valve adopts a double eccentric structure, which has a tighter sealing function as it closes, and its sealing performance is reliable.
2. The sealing material is made of stainless steel and nitrile oil-resistant rubber pairing, which has a long service life.
3. The rubber sealing ring can be located on the valve body or on the butterfly plate, which can be applied to different characteristics of media for users to choose.
4. The butterfly plate adopts a frame structure with high strength, large flow area and small flow resistance.
5. The rectangular pneumatic ventilating butterfly valve is painted as a whole, which can effectively prevent corrosion and can be used in different media as long as the sealing material of the sealing valve seat is changed.
6. The rectangular pneumatic ventilating butterfly valve has a two-way sealing function. It is not controlled by the flow direction of the medium during installation and is not affected by the spatial position. It can be installed in any direction.
7. The rectangular pneumatic ventilating butterfly valve has a special structure, which is flexible, labor-saving and convenient.
8. There are no connecting rods, bolts, etc., so it works reliably and has a long service life. It can be installed in multiple positions, and is not affected by the flow of the medium.
9. The rectangular manual ventilation butterfly valve is specially designed for ventilation and dust removal pipelines. It has the characteristics of short structure, light weight, simple structure, low flow resistance, flexible opening and closing, and convenient maintenance.
10. Rectangular manual ventilation butterfly valves are widely used in the ventilation and dust removal of power stations, metallurgy and mines, and heating and ventilation gas pipelines to adjust and control the medium flow. The light butterfly valve has round butterfly valve, rectangular single plate, rectangular multi-plate butterfly valve. Other light ventilation butterfly valves can be made according to user requirements.
