Model HydraulicsByFluidon.Components.Valves.DirectionalValves.SwitchingValve22
The component SwitchingValve22 is a model of a 2-way valve which will open for input signals equal or above Input threshold to open the valve.
Opening and closing times of the valve are set by Time to close 100 % - 0 %/Time to open 0 % - 100 %, the movement is linear with constant speed until the respective end stop is reached.
The valve stroke can be shifted by Relative overlap. In accordance with common valve parameters a negative overlap will open the valve edge.
The default relationship between input signal and flow rate of the metering edge is linear, but can be changed through the use of a 1D look-up table. The look-up table is provided either manually or by importing a text file. If the parameter Table is provided by file is set to false, the manually entered datapoints from Manually provided look-up table will be used. If it is set to true, the table Table name on file from the file File where look-up table is stored will be utilized.
The text file must follow a specific syntax such that it can be read by Modelica. The input values as well as the output values must lie within the range from 0 to 1. An output value of 1 (100 %) corresponds to a fully-opened metering edge. An example for a properly formatted text file with two tables is given in the figure below:
A table is declared by its datatype (e. g. double), followed by the table name (e. g. tab1) and its dimensions in brackets (e. g. (5,2)). As can be seen, multiple tables can be defined in the same text file. The table declaration is followed by the actual data. The first column of the table represents the input of the 1D table, whereas the second column lists the corresponding output values. The input values of the table must be in increasing order. The component interpolates linearly between the listed input values. More information regarding the format of tables can be found at CombiTable1D.

Model HydraulicsByFluidon.Components.Valves.DirectionalValves.SwitchingValve33
The component SwitchingValve33 is a model of a 3-way valve where the flow (at 100 % valve stroke) is set by NominalVolumeFlow and NominalPressureDifference.
For Input ≥ Input threshold to open the valve the valve switches in positive direction up to right position, for Input ≤ - Input threshold to open the valve the valve switches in negative direction up to left position. For - Input threshold to open the valve < Input < Input threshold to open the valve it switches into resting position (middle position).
The opening of the valve lasts always <>Time to open 0 % - 100 %<>, the closing always <>Time to close 100 % - 0 %<>, i. e. the switching from one end stop position to the other lasts <>Time to close 100 % - 0 %<> + <>Time to open 0 % - 100 %<>.
The valve stroke can be shifted by Valve edge general relative overlap. In accordance with common valve parameters a negative overlap will open the valve edge. Valve edge general relative overlap is applied to all valve edges simultaneously. If at least one of the edge-specific values, e. g. Valve edge PA relative overlap is set to a value different from 0, then Valve edge general relative overlap is ignored and the individual overlaps are used.
The default relationship between input signal and flow rate of the metering edge is linear, but can be changed through the use of a 1D look-up table. The look-up table is provided either manually or by importing a text file. If the parameter Table is provided by file is set to false, the manually entered datapoints from Manually provided look-up table will be used. If it is set to true, the table Table name on file from the file File where look-up table is stored will be utilized.
The text file must follow a specific syntax such that it can be read by Modelica. The input values as well as the output values must lie within the range from 0 to 1. An output value of 1 (100 %) corresponds to a fully-opened metering edge. An example for a properly formatted text file with two tables is given in the figure below:
A table is declared by its datatype (e. g. double), followed by the table name (e. g. tab1) and its dimensions in brackets (e. g. (5,2)). As can be seen, multiple tables can be defined in the same text file. The table declaration is followed by the actual data. The first column of the table represents the input of the 1D table, whereas the second column lists the corresponding output values. The input values of the table must be in increasing order. The component interpolates linearly between the listed input values. More information regarding the format of tables can be found at CombiTable1D.

The component PropValve22PT2TableAx is a model of a 2-way proportional valve where the stroke follows the input signal with a 2nd order delay.
The parameterization of the meetering edge is done by providing the Flow coefficient alphaD and a look-up table of the Cross-sectional area as a function of the input signal. Further information regarding the formatting of the look-up table can be found in the documentation of the component ResistorTableAx.
For a positive stroke, the cross-sectional area of the valve's meetering edge is given as a function of the input signal through a look-up table starting from 0 to maximum area (the cross-sectional area of the valve when it is completely open). The cross-sectional area must be given in m^2. The flow is then calculated based on Flow coefficient alphaD, Cross-sectional area, density of the fluid and pressure difference between the two edges of the valve, according to the formula given below:
The valve stroke can be shifted by Relative overlap general. In accordance with common valve parameters a negative overlap will open the valve edge.

Model HydraulicsByFluidon.Components.Valves.DirectionalValves.PropValve33PT2TableAx
The component PropValve33PT2TableAx is a model of a 3-way proportional valve where the stroke follows the input signal with a 2nd order delay.
The parameterization of the valve is done by providing the Flow coefficient alphaD and a look-up table of the Cross-sectional area as a function of the input signal. Each of the two meetering edges is parameterised with a separate look-up table and a Flow coefficient alphaD given by the user. Further information regarding the formatting of the look-up table can be found in the documentation of the component ResistorTableAx. Unlike the Resistor component, the look-up table for valve edges is declared for the input range from -1 to 1.
For a positive and negative stroke, the cross-sectional area of the valve's meetering edge is given as a function of the input signal through a look-up table starting from 0 to maximum area (the cross-sectional area of the valve edge when it is completely open). The cross-sectional area must be given in m^2. The flow is then calculated based on Flow coefficient alphaD, Cross-sectional area, density of the fluid and pressure difference between the two edges of the valve, according to the formula given below:
The valve stroke can be shifted by Relative overlap general. In accordance with common valve parameters a negative overlap will open the valve edge. Relative overlap general is applied to all valve edges simultaneously. If at least one of the edge-specific values, e. g. Relative overlap PA or -AT is set to a value different from 0, then the Relative overlap general is ignored and the individual overlaps are used.

Model HydraulicsByFluidon.Components.Valves.DirectionalValves.PropValve33PT2TableQpx
The component PropValve33PT2TableQpx is a model of a 3-way proportional valve where the stroke follows the input signal with a 2nd order delay.
The hydraulic parameterization of the valve is done by providing a look-up table of the flow rate as a function of the pressure drop and the input signal. Each of the two meetering edges is parameterised with a separate look-up table given by the user. Further information regarding the formatting of the look-up table can be found in the documentation of the component ResistorTableQpx. Unlike the Resistor component, the look-up table for valve edges is declared for the input range from -1 to 1.
For a positive stroke (right position) the flow is function of input signal (starting from 0 to Input value for 100 % open) and the pressure difference across the valve edge. In case of a negative stroke (left position) the same applies for input from 0 to -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. Relative overlap general is applied to all valve edges simultaneously. If at least one of the edge-specific values, e. g. Relative overlap PA or -AT is set to a value different from 0, then the Relative overlap general is ignored and the individual overlaps are used.

Model HydraulicsByFluidon.Components.Valves.DirectionalValves.PropValve43PT2
The component PropValve43PT2 is a model of a 3-way proportional valve where the stroke follows the input signal with a 2nd order delay.
For a positive stroke (right position), the flow is scaled in proportion to the input signal starting from 0 to Input value for 100 % open with nominal flow (as given by Nominal volume flow/Nominal pressure difference) corresponding to an input value of Input value for 100 % open. In case of a negative stroke (left position) the same applies for input from 0 to -Input value for 100 % open.
The valve stroke can be shifted by Valve edge general relative overlap. In accordance with common valve parameters a negative overlap will open the valve edge. Valve edge general relative overlap is applied to all valve edges simultaneously. If at least one of the edge-specific values, e. g. Valve edge PA relative overlap is set to a value different from 0, then Valve edge general relative overlap is ignored and the individual overlaps are used.
The default relationship between input signal and flow rate of the metering edge is linear, but can be changed through the use of a 1D look-up table. The look-up table is provided either manually or by importing a text file. If the parameter Table is provided by file is set to false, the manually entered datapoints from Manually provided look-up table will be used. If it is set to true, the table Table name on file from the file File where look-up table is stored will be utilized.
The text file must follow a specific syntax such that it can be read by Modelica. The input values as well as the output values must lie within the range from 0 to 1. An output value of 1 (100 %) corresponds to a fully-opened metering edge. An example for a properly formatted text file with two tables is given in the figure below:
A table is declared by its datatype (e. g. double), followed by the table name (e. g. tab1) and its dimensions in brackets (e. g. (5,2)). As can be seen, multiple tables can be defined in the same text file. The table declaration is followed by the actual data. The first column of the table represents the input of the 1D table, whereas the second column lists the corresponding output values. The input values of the table must be in increasing order. The component interpolates linearly between the listed input values. More information regarding the format of tables can be found at CombiTable1D.

Model HydraulicsByFluidon.Components.Valves.DirectionalValves.PropValve43PT2TableAx
The component PropValve43PT2TableAx is a model of a 3-way proportional valve where the stroke follows the input signal with a 2nd order delay.
The parameterization of the valve is done by providing the Flow coefficient alphaD and a look-up table of the Cross-sectional area as a function of the input signal. Each of the four meetering edges is parameterised with a separate look-up table and a Flow coefficient alphaD given by the user. Further information regarding the formatting of the look-up table can be found in the documentation of the component ResistorTableAx. Unlike the Resistor component, the look-up table for valve edges is declared for the input range from -1 to 1.
For a positive and negative stroke, the cross-sectional area of the valve's meetering edge is given as a function of the input signal through a look-up table starting from 0 to maximum area (the cross-sectional area of the valve edge when it is completely open). The cross-sectional area must be given in m^2. The flow is then calculated based on Flow coefficient alphaD, Cross-sectional area, density of the fluid and pressure difference between the two edges of the valve, according to the formula given below:
The valve stroke can be shifted by Relative overlap general. In accordance with common valve parameters a negative overlap will open the valve edge. Relative overlap general is applied to all valve edges simultaneously. If at least one of the edge-specific values, e. g. Relative overlap PA or -AT is set to a value different from 0, then the Relative overlap general is ignored and the individual overlaps are used.
