Valve Packing

Chesterton’s valve packing range is engineered for dependable, low-emission sealing in critical valve applications—from control and isolation valves to steam and process systems. Utilizing advanced materials like high-purity graphite, PTFE, carbon fiber, and premium metallic reinforcements, these packings offer low stem friction, fire-safe performance, and chemical resistance across extreme conditions. Options such as WedgeSeal™, live-loaded assemblies, LowE duplex systems, and GraphMax cater to both dynamic and static sealing needs, ensuring tight control and extended valve life.

For rugged environments and demanding service, Chesterton offers solutions including live-load spacers and cartridge systems that maintain consistent gland compression, injectable sealants for continuous leak prevention, and specialized designs for low emissions and high-temperature performance. Whether addressing high pressure, thermal cycling, or fugitive emissions, Chesterton valve packings minimize maintenance, enhance reliability, and ensure operational integrity.
