Installation

flange connections are correctly aligned to avoid stressing the valve
body.
For the main flanged ports Bolting and Gaskets should comply with the
relevant standard.
All relevant local regulations must also be observed.
5.1.3 Start up
Upon installation and on start up of the system, all parts of the circuit
should be closely monitored to ensure correct performance. A system in
which the valve has been properly selected for the anticipated flows
should operate very closely to the valve’s nominal temperature rating.
Water cooling systems will usually operate at or slightly below the
nominal temperature. Lubricating oils and most other higher viscosity
fluids will operate at or slightly above the nominal temperature.
In any system where the indicated temperatures are more than 2.7°C
(5°F) from the nominal temperature, then an effort should made to
locate the cause.
Any system operating at an indicated 5.5°C (10°F) or more from the
nominal anticipated temperatures may well be malfunctioning and the
cause should be located and rectified immediately. See trouble-shooting
section for possible causes.
