ZhengFeng Valve has always been first-class research and development and production center, is committed to the high temperature and high pressure power station valve exploration, has been designed and applied ZhengFeng high temperature and high pressure power station valve, with wear resistance, high temperature resistance, corrosion resistance, abrasion resistance, long service life.The two ends of the branch pipe are flanged and welded, and the groove of the welding mechanism can be made according to the standard or user's requirement.Suitable for power plant, petrochemical, metallurgy and other high temperature and high pressure water, steam, oil, superheated steam pipe.
High temperature and high voltage power station valve series products:
Welding type power station stop valve, welding type power station stop valve for thermal power plant water, steam channel, valve for the packing chamber and valve body of a lightweight structure, valve structure is simple, easy maintenance;The valve body material has the carbon steel and the chromium molybdenum vanadium steel two kinds, the sealing surface surfacing welds the cobalt base alloy, the valve stem surface USES the anticorrosive nitriding or the electroless plating nickel protection respectively.
High temperature and high voltage power station valve advantages:
1. Pressure self-tightening seal is adopted, and both ends of the branch pipe of the valve body are welded.
2. The sealing surface of valve seat and disc is made of cobalt-based hard alloy surfacing welding or plasma jet welding, with high temperature resistance, abrasion resistance and abrasion resistance.
3. The valve stem has good corrosion resistance and abrasion resistance through corrosion resistance nitriding treatment.
