The service life ofindustrial high pressure valves is related to three factors, one is the quality of the valve itself, the other is the working condition of the valve, and the third is whether the valve is installed and maintained correctly. The quality of the valve itself is related to the raw material, structure and heat treatment process of the valve. Selecting engineering ceramics materials can effectively improve the wear resistance and corrosion resistance of the valve. Heat treatment mostly adopts heat treatment and surface hardening treatment. Personally, I think the former can improve the performance and service life of the valve. We have no choice of working conditions, we can only say that when selecting the type, we must choose the suitable working conditions; correct installation of industrial high-pressure valves, and correct operation and maintenance of valves can also improve the service life of valves.
