Features

This engineering-designed low-emission valve packing set uses a combination of metal wire braided enhanced expanded graphite rings and a highly adaptable core.
The permanent elastic components of the sealing kit ensure that the valve achieves the lowest leakage rate and reduces friction throughout its entire life cycle.

Advantages

The packing is pecifically designed for API 602 Forged High-Pressure Self-Sealing Valves
It offers high-temperature and chemical resistance
It fully complies with the latest fugitive emission regulations
It provides excellent sealing performance and permanent
It demonstrates good anti-extrusion performance under high pressure
Optimized ring configuration: Requires lower compression force, thereby reducing operational stress
