  • Packing for a high-pressure valve
    Patent number: 11898656
    Abstract: A valve bonnet defines a packing box having an inner surface Roughness Average (Ra) of 0.15 or less, for example, between 0.10 and 0.15. Multiple Polytetrafluoroethylene (PTFE) packing rings are in a packing stack. A packer is bolted to the bonnet and extends into the packing box. The packer is configured to apply a packing pressure on the packing, for example, between 100 megapascals (MPa) and 200 MPa. Such arrangements can allow for high pressure valves, for example valves that can retain up to 10,000 pounds per square inch (PSI) of pressure or up to 15,000 PSI.
