Patents Advanced Graphite Pressure Seal Ring Technology

Dongsuh Industry is proud to announce the official patent registration of our innovative Valve Device Technology (Patent No. 10-2360434). This patent marks a significant milestone in our mission to provide high-performance sealing solutions for the most demanding industrial environments.

Innovative Engineering: The Graphite Pressure Seal Ring

The newly patented technology focuses on our specialized Graphite Pressure Seal Ring. Unlike traditional seals, this device features an integrated metal disk spring embedded within the graphite structure.

This hybrid design addresses two critical challenges in valve maintenance and safety:

  • Anti-Loosening Performance: By utilizing the resilience (repulsive force) of the internal spring, the seal effectively counteracts the reduction of tightening pressure over time, ensuring a consistent and secure fit.
  • Enhanced Lip Sealing: The structural reinforcement significantly improves the sealing force of the lower lip section, preventing leaks even under fluctuating pressure conditions.
