  •  Pneumatic high pressure stop valve

Product overview

The pneumatic high-pressure stop valve is generally of welded structure, which is mainly used in the pipelines of various systems in thermal power plants. It is suitable for steam, oil and other media, and has the characteristics of high temperature and high pressure resistance. High pressure pneumatic welding stop valve has good corrosion resistance and sufficient strength. Compared with other valves, it has the characteristics of high temperature and high pressure, unique self sealing design, the higher the pressure, the more reliable the seal.
Advantages of pneumatic high pressure stop valve:
 
1. 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.
2. The depth of the stuffing box of the valve cover is reasonable, the packing is added with corrosion inhibitor, the sealing is reliable and the switch is stable.
3. The valve has upper sealing structure to ensure no leakage through the valve stem when the valve is opened.
4. Both ends of the branch pipe are welded. Welding groove can be matched according to standard or user requirements.

Use and maintenance of high pressure stop valve:
1. After the valve is used, it is necessary to observe the opening and closing status regularly, and deal with the problems found in time;
2. Fill lubricating oil regularly to keep good lubrication condition of all lubricating moving parts;
3. The high density felt must be replaced in time after it is worn or cracked;
4. Always check and maintain the integrity of valve parts.
