进口高温高压截止阀适用与高温高压管道上，阀杆轴线与阀座密封面垂直。阀杆开启或关闭行程相对较短，并具有非常可靠的切断动作，使得这种阀门非常适合作为介质的切断或调节及节流使用。

进口高温高压截止阀优点及用途：

结构紧凑、高度小、维修方便；

阀门与管路连接采用焊接式结构；

流量阻力小、摩擦力小、启闭灵敏；

密封面为硬质合金不易磨损、擦伤、密封性能好；

具有抗气蚀作用，耐磨、耐蚀、耐冲刷，使用寿命长；

适用介质:水、蒸汽、油品管路上及火电厂、核电站、石油化工系统的高温、高压管路等；

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.;
