Carbide valve sealing surface (Hardmetal Valve Seating Surface) refers to the key part used for sealing in the valve, usually made of carbide material.
The valve sealing surface is a key component in the valve. Its main function is to ensure reliable sealing of the valve in the closed state and prevent medium leakage. Since valves often face harsh conditions such as high temperature, high pressure, corrosion and wear during use, it is necessary to use materials with good wear resistance, corrosion resistance and high hardness to form the sealing surface.
Carbide is a material commonly used for valve sealing surfaces. It is a composite material composed of high hardness and high wear resistance materials such as tungsten carbide and titanium carbide. Carbide has excellent hardness, wear resistance and corrosion resistance, and can provide reliable sealing performance under harsh conditions.
During the valve manufacturing process, carbide materials are often coated, overlayed or welded to the valve sealing surface. This treatment can provide a protective layer of carbide and enhance the wear resistance and corrosion resistance of the sealing surface.
The use of carbide valve sealing surfaces can effectively reduce valve leakage and wear, extend the service life of the valve, and improve system reliability. Therefore, carbide valve sealing surfaces are widely used in some applications that require high sealing and durability, such as valve applications in the fields of petroleum, chemical industry, energy and manufacturing.
