Commercially available pressure seals?

[dfteng]

I need to use a pressure seal to seal the body/bonnet joint for a high pressure, high temperature steam control valve application. Are there any pressure seals that are commercially available or is each one a "design to order" type of seal. I am looking for design guidelines for pressure seal joints. Any good books or websites? I saw the thread from last week (1/14) about pressure seals; it was good information.
