Curtiss-Wright’s Industrial Division Farris 3800L Series Pressure Relief Valve Receives ASME Approval

CHRISTCHURCH, UK–(BUSINESS WIRE)–#CurtissWrightValveGroup–Curtiss-Wright’s Industrial division has announced that its Farris
Engineering business unit has received ASME Code Section VIII
certification for the 3800L Series pilot operated pressure relief valves
with modulating pilot controls (PCM) for use in air, gas and vapor
service. Previously, the 3800L was only certified for liquid service.

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 operate 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 with PCM control product
offering, please visit our website.
