Valve balance seal ring material introduction


. What is the valve balance seal ring

The valve balance seal ring is an important sealing part in the valve, which is mainly used to eliminate the unbalance of the sealing surface load caused by the pressure difference of the valve, making the valve seal more reliable. The common valve balance seal ring is mainly made of metal and non-metal materials.

. The valve balance seal ring material

1. Metal material

The metal valve balance seal ring is mainly made of stainless steel, superalloy and nickel-based alloy and other materials, with good high temperature resistance, corrosion resistance, wear resistance and other properties, especially suitable for high temperature, high pressure and other harsh conditions of the valve.

 

2. Non-metal material

Non-metallic valve balance sealing ring is mainly polytetrafluoroethylene (PTFE), polyimide, polymethyl methacrylate and other materials, with good sealing, chemical resistance and temperature resistance, usually suitable for low temperature, low pressure valve.

. The choice of valve balance seal ring

The material selection of the valve balance seal ring should be comprehensively considered according to the specific working conditions and use requirements of the valve. Under normal circumstances, the metal valve balance seal ring is suitable for high temperature and high pressure fluid media, while the non-metal valve balance seal ring is suitable for low temperature and low pressure media. In addition, the tightness and life of the valve are also affected by the material of the balance seal ring, and the appropriate material should be selected according to the specific working conditions.

 

. Conclusion

When selecting the material of the valve balance seal ring, it should be comprehensively considered according to the specific working conditions and use requirements of the valve, and the selection of the appropriate material can effectively improve the sealing performance and service life of the valve. The metal and non-metal valve balance seal rings have their own advantages and disadvantages, and the appropriate material should be selected according to the specific conditions.
