Two way valve with nonlinear opening characteristics based on a table

## Information

Test 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.

## Revisions

- August 12, 2014 by Michael Wetter:
  Added `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.
- April 2, 2014 by Michael Wetter:
  First implementation.
