Industry Applications

BOPIN focus on manufacturing all types of industrial valves such as forged steel valves, forged steel ball valves, bellows sealed valves, triple offset butterfly valves, plug valves, etc. especially the corrosion resistance valves. The main reason for choosing anti-corrosion valves is their excellent corrosion resistance and long service life. 316L stainless steel, Hastelloy, titanium alloy and other highly corrosion-resistant materials can effectively resist the erosion of various corrosive media, extend the service life of valves, and reduce maintenance costs. In addition, anti-corrosion valves also have high sealing performance and stable control accuracy, which can meet various complex working conditions. The application fields of BOPIN valves are very extensive, mainly including the following major industries:

Oil & Gas

Steam Systems

Water System

Chemical Industry
