| The SD61H-P57.655V isolation valve self-sealing ring is a sealing component designed for high temperature and high pressure environments. It uses high-quality graphite and stainless steel composite materials. Graphite has become the core material of the sealing ring with its excellent high temperature resistance, high pressure resistance, self-lubrication and chemical stability, ensuring the durability and reliability of the sealing effect. At the same time, the addition of stainless steel further enhances the strength and corrosion resistance of the sealing ring, allowing it to maintain excellent performance under harsh working conditions. In terms of customized processing, we provide a full range of personalized services. The size can be precisely customized according to the actual needs. This flexibility ensures that the self-sealing ring can perfectly adapt to various high-pressure isolation valves to meet the sealing needs under different working conditions. |
| Working Principle: The working mode of the isolation valve self-sealing ring is based on its unique structure and material characteristics. When the isolation valve is closed, the self-sealing ring is subjected to the pressure of the valve, and the graphite material can fit tightly on the valve seat surface due to its good flexibility and rebound coefficient, forming a reliable seal. |
| Product Features Use high-quality graphite and stainless steel composite materials to ensure the durability and reliability of the sealing effect. Excellent high temperature and high pressure resistance. Strong corrosion resistance, able to resist the erosion of various corrosive media. Provide a full range of personalized customization services, which can perfectly adapt to various high-pressure heater plugging valves. Easy to install and maintain, reducing the difficulty and cost of operation. |
| Application Widely used in the reheater system of power station boilers, especially in the steam pipes at the outlet of boiler superheater and the inlet and outlet of reheater. The valve is suitable for various high temperature and high pressure working conditions, such as the main steam pipeline of thermal power generating units, and occasions requiring static water pressure test. In addition, the valve can also be used in other industrial fields that require high temperature and high pressure sealing, such as chemical, oil refining, steel and other industries. |
