Ventilation butterfly valve is a non-sealed butterfly valve, mainly used in ventilation systems. This kind of valve is designed and manufactured using a new structural form welded by a centerline butterfly plate and a short structural steel plate. It has the advantages of compact structure, light weight, easy installation, small flow resistance, and large flow capacity. Its characteristics are as follows:

1. Ventilation butterfly valves are suitable for pipes with a medium temperature of ≤300°C and a nominal pressure of 0.1Mpa in the production processes of building materials, metallurgy, electric power, etc., to connect, open and close or regulate the flow of the medium.

2. The ventilation butterfly valve has good sealing performance under low pressure and can transport mud and reduce the accumulation of liquid at the pipe mouth.

3. The ventilation butterfly valve adopts a soft seal design. The sealing pair is composed of non-metallic soft materials or metal hard materials on non-metallic soft materials. It has the advantages of good adjustment performance, convenient and rapid opening and closing, labor saving, and low fluid resistance.

4. There are no connecting rods, bolts and other parts in the ventilation butterfly valve, so it works reliably and has a long service life.

5. The accessories of the ventilation butterfly valve include manual mechanisms, air source treatment accessories, etc., which are convenient for users to operate and control.

Ventilation butterfly valve has a wide range of applications and is an important part of the ventilation system. Understanding its product description and characteristics will help you better select and use this valve and improve the performance and reliability of your ventilation system.
