6800 Valve Packing

Control Valve Packing Set That Outperforms ISO 15848 Standard by More Than Three Times

Control and isolation valves are one of the most friction-sensitive applications to seal. These pieces of equipment can become particularly vulnerable to high packing friction, resulting in an overall decrease in system efficiencies and reduced production outputs.

Chesterton’s new control valve packing fits natural gas and oil processing applications.

Chesterton® 6800 LowE Packing Set uses the design of the 5800 series packing, combining graphite’s stability with PTFE’s low friction. It incorporates the unique Chesterton WedgeSeal™ design with a graphite/PTFE hybrid material featuring a thermally stable base of pure graphite tape over-knitted with pure PTFE filament.

The packing set utilizes hybrid braided material against the stem’s dynamic surface where friction is highest. Static sealing components incorporate Chesterton’s pure graphite tape with a passive corrosion inhibitor.

The 6800 LowE Packing Set meets today’s difficult sealing requirements from all state and federal regulations for low VOC and VHAP emissions.

Also available in Kit form.
