Partial model for valves with different opening characteristics, such as linear, equal percentage or quick opening. This partial extends from AixLib.Fluid.Actuators.BaseClasses.PartialTwoWayValve and also contains the governing equations for these three two way valve models.
Models that extend this model need to provide a binding equation
for the flow function phi. An example of such a code
can be found in AixLib.Fluid.Actuators.Valves.TwoWayLinear.
