Imported high-temperature and high-pressure shut-off valve for high temperature and high pressure pipe, the stem axis and vertical seat sealing surface. Stem to open or close the relatively short trip, ａnd has a very reliable cutting action makes this valve very suitable as a medium cut or regulation and throttle use.
Advantages and use of imported high-temperature and high-pressure shut-off valve:
Compact structure, the height of a small, easy maintenance;
Valves and piping connections welded structure;
Flow resistance, friction is small, sensitive and open and close;
The sealing surface of the carbide is not easy to wear, abrasions, good sealing performance;
With anti-cavitation, wear-resistant, corrosion-resistant, resistant to erosion ａnd long service life;
Suitable medium: water, steam, oil pipelines and thermal power plants, nuclear power plants, petrochemical high temperature, high pressure piping, etc.;
