Features

This low-emission valve packing set utilizes a woven metal wire-reinforced expanded graphite ring with a highly adaptable core.
The permanent elastic components of the sealing kit ensure minimal leakage rates and reduced friction throughout the valve's lifecycle.
Specifically designed for low-emission valve applications.

Advantages

High-temperature resistance and chemical resistance
Full compliance with the latest fugitive emission regulations
Excellent sealing performance and permanent elasticity
Good anti-extrusion performance under high pressure
Optimized ring configuration requires lower compression force
