Relieving Temperature INTRODUCTORY NOTES COLD DIFFERENTIALTEST PRESSURE TOLERANCE The tolerances on the cold differential test pressure are the following: Up to 3,7 bar ±4% or ±0,04 bar whichever is greater over 21 bar ±1% orO, 7 barwhichever is greater MINIMUM COLD DIFFERENTIAL TEST PRESSURE (SPRING SETTING) The minimum cold differential test pressure is shown in the following table. For conventional valves with special construction, the minimum cold differential test pressure can be reduced to 0,4 bar.

SERIES SMU-7000 VALVES Nozzle-disc seats manufactured by UKLAST are of the metal to metal type. They can be supplied hardened (with stellite or made in 174PH) or resilient (with o-ring). The most frequent cases in which these constructions are requested are: 1) hardened when the media is dirty, may crystallize or contain solids 2) hardened for medium and high pressure depending on the temperature, see following diagram 3) resilient when requested by client UKL AST will suggest the best solution for each operating condition.
