Product Overview
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 °C. The applicable media are water, oil, steam, etc. Operation mode: manual, gear
transmission, electric, etc.
Structural Characteristics
- The connection between valve and pipeline adopts flange structure.
- 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.
- 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.
- Compact structure, good opening and closing, small height and convenient maintenance.
- The valve cover packing box is reasonable, the packing is added with corrosion inhibitor, the sealing is reliable and the switch is stable.
- The valve has upper sealing structure to ensure that the valve stem will not leak when the valve is opened.
