What are some good domestic brands of wear-resistant valves?
Thread Content
As the title suggests, what are some good wear-resistant valve brands available in China? Do you know any of them?
Wear-resistant valves for coal chemical industry: For cut-off valves, there are companies such as Shanghai Hongsheng and Suzhou Antewei. Regulating valves are produced by companies such as Shanghai Datong, the 11th Aerospace Research Institute, and Shanghai No. 7 Factory.
What about the imported ones? It seems that there are relatively few applications that require wear resistance, so the market is small, and not many companies specialize in producing products with wear-resistant properties
It depends on the medium flowing through your pipeline; the common practice is to apply an anti-wear coating to the inner wall of the pipe
In applications where wear-resistant valves are used and where pressure and temperature levels are not high, pipe clamp valves represent a good choice; however, ones made in China of poor quality should be avoided. As far as I know, there is American Red Valve, and FLOWROX from Finland (formerly known as Laloxx)
Domestically produced clamp valves don’t seem to be of good quality. Imported ones are too expensive; ordinary customers can’t accept them
For harsh operating conditions, it’s better to use reliable imported products
Currently, there are several types of wear-resistant valves. One type consists of a metal substrate to which hard alloys such as tungsten carbide and Stellite alloy are sprayed on; such valves are suitable for use in situations where wear is not severe, but they cannot be used in acidic environments. Another type is made of structural ceramics, such as zirconia ceramic or silicon carbide ceramic. These ceramics are sintered in a single step, without any spraying, and they take advantage of their properties as inorganic non-metallic salts, offering wear and corrosion resistance. They are suitable for use in environments with both acidic and alkaline wear. In China, Yantai Jintaimelin is a company that does well in this area.
