When comparing the durability of ceramic valves and metal valves, we can conduct a detailed analysis and summary from the following aspects:

Wear resistance:

Ceramic valves: Due to the extremely high hardness and wear resistance of ceramic materials, ceramic valves can operate stably for a long time when dealing with media containing solid particles, dust, or strong wear resistance. For example, ceramic valves have better wear resistance than metal valves and can withstand longer periods of wear and tear.

Metal valves: The wear resistance of metal materials is usually lower than that of ceramic materials, especially when dealing with high hardness particle media, metal valves are prone to problems such as wear and scratches.

Corrosion resistance:

Ceramic valves: Ceramic materials have excellent chemical stability and can resist the erosion of various chemical corrosive media. Therefore, ceramic valves can maintain stable performance and longer service life when dealing with highly corrosive media such as acids, alkalis, and salts.

Metal valves: Although some metal valves also have certain corrosion resistance, their corrosion resistance is inferior compared to ceramic valves. The resistance to corrosion varies among different metal materials and alloy compositions, but generally speaking, metal valves are susceptible to corrosion in corrosive media.

Sealing performance:

Ceramic valve: The surface of ceramic material is smooth, with high hardness and good sealing performance. Ceramic valves can achieve zero leakage sealing effect and improve the reliability of the valve.

Metal valves: The sealing performance of metal valves is affected by various factors such as materials, manufacturing processes, and installation quality. Although some metal valves also have good sealing performance, their sealing performance may be slightly inferior compared to ceramic valves.

service life:

Ceramic valves: Due to the wear-resistant and corrosion-resistant properties of ceramic materials, the service life of ceramic valves is usually longer than that of metal valves. In some harsh working conditions, the service life of ceramic valves can reach more than 20 years.

Metal valves: The service life of metal valves is influenced by various factors such as usage environment, material selection, production process, use and maintenance, and installation quality. In general, the service life of metal valves is about 10 years, but the actual life may vary due to various factors.

Maintenance and upkeep:

Ceramic valves: With proper use and maintenance, the service life of ceramic valves can be further extended. For example, measures such as using clean purified water, regular inspections, regular cleaning, avoiding moisture and excessive use can effectively extend the service life of ceramic valves.

Metal valves: During use, it is also necessary to pay attention to the correct usage method and timely maintenance of metal valves. For example, avoiding excessive opening and closing, overloading or improper operation, regularly cleaning, lubricating and inspecting valves can all extend the service life of metal valves.

In summary, ceramic valves have significant advantages in wear resistance, corrosion resistance, and sealing performance, and their service life is usually longer than that of metal valves. However, when selecting valves, specific usage environments and requirements, as well as factors such as cost and efficiency, need to be considered. Under certain operating conditions, metal valves may still be a suitable choice.
