The valve body and valve seat sealing surface are built up using different hardness grades of Stellite cobalt-based hard alloy. The sealing of the stainless steel dark rod high-temperature corrosion resistant slide valve is reliable, with high hardness, wear resistance, high-temperature resistance, corrosion resistance, and good anti-scratch performance, leading to a long service life. It is extensively used in various fields such as chemical plants, power plants, metallurgy, petrochemicals, construction, drainage, municipal, and others.
