Applicable medium: water, oil, steam, etc. The operation modes are: manual, gear transmission, electric and so on.Structural characteristics of high temperature chromium-molybdenum steel gate valve1. 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.Material description of main parts of high temperature chromium-molybdenum steel gate valveBodyWCBA105Cr5MoZGCr18Ni9TiBonnetWCBA105Cr5MoZGCr18Ni9TiSupportWCBA105Cr5MoZGCr18Ni9TiFlashboardWCB25Cr5MoZGCr18Ni9TiStem2Cr132Cr1338CrMoA1,25Cr2MoV1Cr18Ni9TiSeat2525304304Seal ring304,Enhanced flexible graphitePackingEnhanced flexible graphiteStem nutZCuA110Fe3
