Low Emission Gate Valve Packing Set Features

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

Low Emission Gate Valve Packing Set​ 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
