[Valve Features]
1, The valve in the middle of the pressure from the tight seal structure, good sealing performance.
2, The valve, the sealing surface of the valve seat with cobalt-based carbide welding, wear, high temperature, anti-scratch performance, long service life.
3, Stem corrosion by nitriding treatment, a good corrosion resistance and scratch resistance.
4, Anti-high temperature creep design.
5, The valve cover packing depth is reasonable, filler plus corrosion inhibitor, sealed and reliable.
6, The valve has a sealed structure to ensure that the valve is running when the valve stem will not leak.
7, The valve drive mode Manual, gear drive, electric, remote control and automation can be achieved.
[Adaptation]
Power station gate valve (main steam gate valve) for thermal power plants, petrochemicals, metallurgy and other high temperature and high pressure water, steam, oil, superheated steam on the pipeline.
