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.
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.

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.
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.
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.
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.

This butterfly valve is a new generation of wear-resistant triple-eccentric metal hard-sealing butterfly valve researched and developed by the company by absorbing and understanding foreign technologies
Bi-directional metal sealing butterfly valve was researched and developed by the company in 1993, which was granted with national patents (ZL93203934.0, ZL98242105.2) twice.
Bi-directional rubber sealing butterfly valve was researched and developed by our factory in 1991. Through continuous improvement, the product performance has been in the leading position at home and abroad.
