Product features and applications: This valve is a specialized valve designed for powdered and granular media pipelines in melamine process systems. During the valve closing process, the V-shaped port moves tightly against the valve seat to scrape away crystals and impurities from the sealing surface, ensuring the reliable sealing of the valve. 2. The surface of the V-shaped sphere is sprayed with tungsten carbide high hardness coating using supersonic flame spraying technology, and the sealing surface of the valve seat is welded with Stellite hard alloy, which is resistant to erosion and wear. 3. According to the needs, insulation sleeves can be added to the valve to insulate it with high-temperature gas, preventing material crystallization on the inner wall of the shell.
