Gate Valve

Widely used in fields such as petroleum, chemical engineering, metallurgy, construction engineering, water supply, etc

1. Meet the requirements of advanced domestic and international standards, with reliable sealing, excellent performance, and beautiful appearance. 2. The sealing surfaces of the gate and valve seat are made of iron based alloy surfacing or Stellite cobalt based hard alloy surfacing, which is wear-resistant, high-temperature resistant, corrosion-resistant, with good scratch resistance and long service life. 3. Adopting a wedge type elastic gate structure, with medium to large diameter rolling bearings, the switch is flexible and easy to open and close. 4. The valve stem has undergone tempering and surface ammoniation treatment, providing excellent corrosion resistance, scratch resistance, and wear resistance. 5. Various piping flange standards and flange sealing surface types can be used to meet various engineering needs and user requirements. 6. The valve body material variety is complete, and fillers and gaskets can be reasonably selected according to actual working conditions or user requirements, which can be suitable for various pressure, temperature, and medium working conditions
