Installation

5.1.2 Mounting the Valve in the Pipe
The valve may be mounted in any orientation; but should be
adequately supported and not subjected to excessive bending and/or
stress. Ensure the pipe 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 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.
