Suitable for water, steam oil pipeline, has the characteristics of resistance to high temperature and high pressure.
Product structure features:
A welding structure used to connect the valve and pipelines.
Sealing surface is not easy to wear, abrasion, good sealing performance, long service life.
Compact structure, good opening and closing, small height, easy maintenance.
The high temperature and high pressure cut-off valve opening and closing is plug valve, sealing surfaces appear flat or cone, disc make linear movement along the centerline of fluid. Stem form of exercise, there is lifting lever (valve rod, the handwheel don't lift), there are also lift rotating lever (hand wheel rotating lifting with the valve stem and nut in the body). Applicable to the nominal pressure PN10.0 ~ 32.0 Mpa and P (54) 100 v ~ 170 v (57), P working temperature 540 ℃ or less (P (57) of whom 170 v working temperature is 570 ℃) of petroleum, chemical industry, water
