Information on the use of the diagram
The temperature / pressure diagram is only an orientation
aid. The data refers to water as a working medium. A
change of operating conditions or other media may result
in deviations. In case of doubt it is advisable to test the
behavior of the material under the definitive operating
conditions by means of a test installation.
Temperatures under 0 °C can affect the operating speed
negatively.
