When sizing valves for media other than water, note that the medium properties
∂ specific heat
∂ density
∂ kinematic viscosity
differ from water. All variables depend on temperature.
The design temperature is the lowest medium temperature in the valve.
Viscosity may change considerably on temperature changes depending on the medi-
um. Plant functionality may be impaired if the medium temperature does not guarantee
viscosity values compatible with troublefree valve functioning.
Kinematic viscosity τ [mm
2
/s] in HVAC plants always is lower than 10 mm
2
/s, i.e. its
influence on volume flow is negligible.
