Description

The component PropValve22PT2TableQpx is a model of a 2-way proportional valve where the stroke follows the input signal with a 2nd order delay.

The hydraulic parameterization of the meetering edge is done by providing a look-up table of the flow rate as a function of the pressure drop and the input signal. Further information regarding the formatting of the look-up table can be found in the documentation of the component ResistorTableQpx.

For a positive stroke, the flow rate is increased with increasing input signal starting from 0 to Input value for 100 % open with maximum flow corresponding to an input value of Input value for 100 % open.

The valve stroke can be shifted by Relative overlap general. In accordance with common valve parameters a negative overlap will open the valve edge.
