The addition of air, gas and vapor certification allows for the
Farris 3800L with PCM control to be ASME Code stamped for use in
both compressible and non-compressible services. The availability
of a pilot operated relief valve certified for both compressible
and non-compressible services provides for an attractive option in
applications that can experience two-phase flow. Operators
typically have to choose between using a liquid or vapor certified
pressure relief valve which will generally only perform properly
under one type of service fluid. The 3800L with PCM control offers
plant operators greater assurance that the relief valve will
operated as intended during an overpressure situation in both
compressible and non-compressible services.
When the 3800L is used for more than one fluid type or for two
phase flow applications, the nameplate may be marked with both an
air and liquid certified capacity and ASME Code Stamped. There is
no change in the overall valve design or spring selection. Valve
opening pressure remains within ASME Code tolerances regardless of
the relieving fluid condition. To learn more about Farris’ 3800L
