In what environment are metal sealed gate valves used?

In what environment are metal sealed gate valves used? In high-temperature environments, hard-sealed gate valves perform well. For example, in the steam pipeline system of a thermal power plant, the steam temperature is often as high as hundreds of degrees. The sealing surface of the hard-sealed gate valve is made of special hard alloy material, which can withstand the test of high temperature and will not cause the sealing performance to decline due to excessive temperature, ensuring that the steam will not leak and ensuring the stable operation of the entire power generation system.

High-pressure environment is also where hard-sealed gate valves come into play. In the high-pressure pipelines of the petrochemical industry, the pressure can reach tens or even hundreds of MPa. The structural design of the hard-sealed gate valve enables it to withstand huge pressures. The hard sealing structure between its gate and valve seat can still maintain a tight fit under high pressure, effectively preventing medium leakage, and providing a guarantee for the safety and stability of chemical production.

metal sealed gate valves are also applicable in environments containing particles or abrasive media. In material conveying pipelines in mining, metallurgy and other industries, the medium often contains a large amount of solid particles. The sealing surface of ordinary valves is easily worn by particles, resulting in seal failure. The hard sealing surface of the hard-sealed gate valve has good wear resistance, can resist the erosion and wear of particles, extend the service life of the valve, and ensure the normal operation of the pipeline system.

In addition, in some environments with extremely high requirements for sealing, hard-sealed gate valves are also indispensable. For example, in the pipeline systems of the food and pharmaceutical industries, in order to prevent the medium from being contaminated, the valve needs to have good sealing performance. The hard-sealed gate valve can meet this requirement and ensure the purity of the medium and the sanitation and safety of the production process.
