Square ventilation butterfly valve

Square ventilation butterfly valve is a type of pneumatic ventilation butterfly valve. The flange of the pneumatic ventilation butterfly valve is square, and it is generally ordered according to the inner diameter.

The square ventilation butterfly valve is made of steel plate welding, with a short structural size, light weight, convenient installation, low flow resistance, large flow capacity, avoiding the influence of high temperature expansion, and easy operation. The expansion gap between the butterfly plate and the valve body is large, which can prevent jamming caused by thermal expansion and contraction. Rectangular pneumatic ventilation butterfly valve is a non closed type butterfly valve widely used in industrial pipelines such as metallurgy, chemical engineering, power, building materials, and mining, to control or regulate the medium gas.

The characteristics of square ventilation butterfly valves:

1. The square ventilation butterfly valve adopts a double eccentric structure, which has a tighter sealing function and sealing performance.

2. The sealing pair is made of stainless steel and nitrile oil resistant rubber, which have a long service life.

3. The rubber sealing ring can be located on the valve body or on the butterfly plate, and can be suitable for different characteristics of media for users to choose from.

4. The butterfly plate adopts a frame structure, with a large flow area and low flow resistance.

5. The square ventilation butterfly valve is painted as a whole, which can prevent rust and can be used in different media as long as the sealing material of the valve seat is changed.

6. The square ventilation butterfly valve has a bidirectional sealing function, and is not controlled by the flow direction of the medium or affected by the spatial position during installation. It can be installed in any direction.

7. The square ventilation butterfly valve structure is flexible, labor-saving, and convenient to operate.

8. There are no connecting rods, bolts, etc. inside, and the service life is long. It can be installed at multiple workstations without being affected by the flow direction of the medium.

9. The square ventilation butterfly valve is specifically designed for ventilation, environmental protection, 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. Square ventilation butterfly valves are widely used in power plants, metallurgy, mining ventilation and dust removal, environmental protection, heating and ventilation gas pipelines for regulating and controlling medium flow. This lightweight butterfly valve comes in the forms of circular butterfly valve, rectangular single plate butterfly valve, and rectangular multi plate butterfly valve. And other lightweight ventilation butterfly valves can be made according to user requirements.
