Permanent Sealing, Leakage Elimination：The valve and pipeline are fused into an integral whole by welding, completely eliminating the gasket—the biggest potential leakage point in flange connections—and achieving permanent sealing.
Integral Structure, Extreme Condition Resistance：Welded joints can withstand higher pipeline stress, severe temperature cycles and mechanical vibrations.
2.Working Principle & Advantages of Pressure Self-sealing Design
Different from traditional forced sealing, the valve seat or sealing structure of the self-sealing design utilizes the pressure of the system medium itself. When the pipeline pressure rises, the medium pressure acts on the specially designed valve disc or sealing ring, pressing it more tightly against the sealing surface. The higher the pressure, the greater the sealing force.
This design ensures that the valve’s sealing performance under high-pressure conditions is even better than that under low-pressure conditions, making it ideal for high-pressure systems. Meanwhile, it can automatically compensate for minor wear on the sealing surface, achieving an "tighter seal under higher pressure" effect, significantly extending the sealing service life and reducing maintenance requirements.
This combined design enables the valve to go beyond its simple function of non-return protection and evolve into a core safety barrier that safeguards critical pipelines operating under high-risk, high-pressure and long-cycle conditions.
Long-Term Stable Operation Guarantee：It delivers a once-and-for-all solution for scenarios requiring decades of maintenance-free service or where maintenance is extremely challenging, such as nuclear power plants and deep-sea pipelines.
Extreme Operating Condition Adaptability：It perfectly withstands harsh conditions that accelerate the aging of traditional seals and the loosening of bolts, including high-temperature thermal cycling, cryogenic environments and high-pressure fluctuations.
