Ventilation butterfly valve
The butterfly valve shall be welded with high quality steel plate, with simple structure, light weight, easy use and maintenance. It is non-sealed, used for regulating medium flow, and applied in metallurgy, mining, cement, chemical engineering, power generation and other industries for ventilation and dust removal, environmental protection and heating ventilation.

Rotary ball valve (Ball-type butterfly valve)
Most valves in the pipe network system are mainly used to cut off and adjust the media. Such valves account for a large proportion and a large amount in the whole system.

Theft-proof butterfly valve
Due to the adoption of double theft prevention design, the product has good theft prevention effect. The valve cannot be opened or closed without the special key.

Welded butterfly valve
The butt-welded bi-directional sealing butterfly valve is mainly used in petroleum, chemical engineering, power station, metallurgy, papermaking, water heating, light industry and other fields, as a shutoff and regulation device on the pipeline.

Clamp butterfly valve
Soft-sealing butterfly valve is suitable for water supply and drainage pipelines and gas pipelines for food, medicine, chemical engineering, petroleum, electric power, textile, paper and others with the temperature ≤120°C and nominal pressure ≤1.6Mpa, playing the role of flow regulation and medium blocking.

Flange connected butterfly valve
The most important thing is to select valves with correct dimension and type. The structure principle of expansion butterfly valve is especially applicable to the manufacturing of large-caliber valve.
