You only know that I sell valves, but you don’t see any valves. He has what he calls the lowest price. I have my ex-factory price. You deny his valves. I have my price-performance ratio. You think my quality is not good. I have my shelf life. Making valves is destined to be a lonely journey, and competition is inevitable on the road. So what, if there is quality, low price, and guarantee, I still live a beautiful life. I am Tianjin Steel Valve, and I take it with me.

3 Flange rubber-lined butterfly valve body, valve disc coating, that is, the medium flow part, are not in direct contact with the valve body, and adopt the form of integral coating.
It has been widely used in the field. In the known butterfly valve technology, the sealing form mostly adopts a sealing structure, and the sealing materials are rubber, polytetrafluoroethylene, etc. Due to the limitations of structural characteristics, it is not suitable for industries such as high temperature resistance, high pressure resistance, corrosion resistance, and wear resistance. An existing relatively advanced butterfly valve is a triple-eccentric metal hard-seal butterfly valve. The valve body and valve seat are one-piece components, and the sealing surface layer of the valve seat is overlay-welded with temperature-resistant and corrosion-resistant alloy materials. Multi-layer soft stacked sealing rings are fixed on the valve plate. Compared with traditional butterfly valves, this kind of butterfly valve has high temperature resistance, is easy to operate, and has no friction when opening and closing. When closing, the torque of the transmission mechanism increases to compensate for the seal, which improves the performance of the butterfly valve. Excellent sealing performance and extended service life.
