modelTwoWayValves
Two way valves with different opening characteristics
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
Test model for two way valves. Note that the leakage flow rate has been set to a large value and the rangeability to a small value for better visualization of the valve characteristics. To use common values, use the default values.
The parameter filterOpening is set to false,
as this model is used to plot the flow at different opening signals
without taking into account the travel time of the actuator.
