Body seal gaskets create pressure barriers at bolted valve body joints in split-body ball valve designs. Cryogenic gaskets use spiral-wound metal with PTFE filler, expanded graphite, or solid PTFE. Gasket selection depends on pressure rating, temperature extremes, and fire safety requirements. Proper bolt torque and gasket compression ensure sealing effectiveness.
