The high pressure globe valve is suitable for the pipeline of various systems in petroleum, chemical, hydraulic and thermal power plants with nominal pressure of 900 ~ 2500lb and working temperature ≤ 540 ℃. The applicable media are water, oil, steam, etc. Operation mode: manual, gear transmission, electric, etc.
1. The connection between valve and pipeline adopts flange structure.
2. The pressure self tightening sealing structure is adopted in the middle chamber of the valve, and the higher the inner pressure, the better the sealing performance.
3. The sealing surface of valve disc and valve seat is made of Slite Stellite cobalt base cemented carbide, which is wear-resistant, high-temperature resistant, scratch resistant and has long service life.
4. Compact structure, good opening and closing, small height and convenient maintenance.
5. The valve cover packing box is reasonable, the packing is added with corrosion inhibitor, the sealing is reliable and the switch is stable.
6. The valve has upper sealing structure to ensure that the valve stem will not leak when the valve is opened.
