Structural characteristics of high temperature chromium-molybdenum steel gate valve
1. It meets the requirements of advanced standards at home and abroad. It has reliable sealing, excellent performance and beautiful appearance.
2. The sealing surface of gate and seat is made of iron-based alloy surfacing or Stellite cobalt-based cemented carbide surfacing. It is wear-resistant, high temperature-resistant, corrosion-resistant and abrasion-resistant.
Good performance and long service life.
3. The valve stem has good corrosion and abrasion resistance after conditioning and surface nitriding treatment.
4. The wedge-type elastic gate structure is adopted, and rolling bearings with medium and large caliber are installed, so the friction is small and the opening and closing are easy.
5. Various piping flange standards and flange sealing surface types can be adopted to meet various engineering needs and user requirements.
