4.2 BODY SEAL
Sealing between the threaded body is provided by a gasket (Teflon or graphite) and both valve segment
surfaces also provide metal to metal friction fit sealing. In larger sizes or higher pressures an elastomer
o-ring may also be used. In case of slight leakage check the threaded body joint is properly tightened up.
If a gasket seal is disturbed while removing or adjusting gasketed parts, APV
recommends installing a new gasket while reassembling. A proper seal is required
to ensure optimum operation.
