Uses and characteristics: 

 The scientific and technical personnel of the company after many years of research and development to design a reported dust coal, clean coal gas, heat and flue, and other dusty gas pipeline, after years of use the effect significantly. Special materials and high-tech corrosion resistance to prevent the smoke to go to achieve flexible switch to death. This valve is mainly used for opening and closing with the dusty gas, clean gas, flue and high-temperature dusty gas pipeline.
