Flange rising stem high temperature and high pressure gate valve

Flange rising stem high temperature and high pressure gate valveProduct Overview:

The gate valve with high and medium pressure flange connection is suitable for cutting off or connecting pipeline media in various systems of petroleum, chemical, hydraulic, and thermal power plants with nominal pressure PN1.6~16.0MPa and working temperature ≤ -29 ℃~550 ℃. Applicable media include water, oil, steam, acid, alkali, ammonia, urea, sulfur-containing natural gas, etc. The operation modes include manual, gear transmission, electric, pneumatic, etc.

Flange rising stem high temperature and high pressure gate valveStructural features:

1. The selection of materials is meticulous, in compliance with relevant domestic and international standards, and the overall quality of the materials is high.
2. Meets the requirements of * standard, with reliable sealing, excellent performance, and beautiful appearance.
3. The sealing pair is advanced and reasonable, and the sealing surfaces of the gate and valve seat are made of Stellite cobalt based hard alloy with different hardness by welding. The sealing is reliable, with high hardness, wear resistance, high temperature resistance, corrosion resistance, good scratch resistance, and long service life.
4. The valve stem has undergone quenching and surface nitriding treatment, exhibiting excellent corrosion resistance, abrasion resistance, and wear resistance.
5. Adopting a wedge-shaped elastic gate structure, thrust bearings are installed on the medium and large diameters, with low friction and equipped with an impact handwheel for easy and smooth opening and closing.
6. Various piping flange standards and flange sealing surface forms can be adopted to meet various engineering needs and user requirements.
