Product features

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 pressure resistance. High pressure pneumatic welding stop valve has good corrosion resistance and sufficient strength. Compared with other valves, it is characterized by high temperature and high pressure, and unique self sealing design. The higher the pressure, the more reliable the sealing.
Advantages of pneumatic high-pressure stop valve:
 
1. The middle chamber of the valve adopts a pressure self tightening sealing structure, and the higher the pressure of the inner chamber, the better the sealing performance.
2. The depth of the valve cover stuffing box is reasonable, the packing is added with corrosion inhibitor, the sealing is reliable, and the switch is stable.
3. The valve has an upper sealing structure to ensure that the valve will not leak through the valve stem when it is opened and operated.
4. Both ends of the branch pipe are welded structures. The welding groove can be matched according to standards or user requirements.

Use and maintenance of pneumatic high-pressure stop valve:
1. After the valve is used, the opening and closing operation condition shall be observed regularly, and problems found shall be handled in time;
2. Add lubricating oil regularly to maintain good lubrication conditions for all lubricating moving parts;
3. The high-density felt must be replaced in time after major wear or tear;
4. Frequently check and maintain the integrity of valve parts.
