.Annex60.Fluid.Actuators.Valves.Examples.TwoWayValveTable .Annex60.Fluid.Actuators.Valves.Examples.TwoWayValveTableTest model for a two way valve in which a table is used to specify the opening characteristics. The valve has the following opening characteristics, which is taken from a test case of the IEA EBC Annex 60 project.
| y | 0 | 0.1667 | 0.3333 | 0.5 | 0.6667 | 1 |
| Kv | 0 | 0.19 | 0.35 | 0.45 | 0.5 | 0.65 |
The Kv value is the volume flow rate in m3/h at a pressure difference of 1 bar. Hence, the Kv value of the fully open valve is Kv=0.65.
Plotting the variables kv.y versus y.y shows that the valve
reproduces the Kv values shown in the above table.
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.

parameter keyword to datVal,
as this is needed to asssign datVal to a parameter
in the instance valTab.
This also avoids an error in OpenModelica.
