New features of SAMSON Valve Sizing Program version 4.7

* New noise reduction measure: Flow Divider II.
* Changes for Vista (HTML-Help).
* Thermodynamic calculation of density at outlet (with database mediums).
* Graphical representation of characteristic can be included in documentation.

version 4.5
* The medium database with more than 1000 process media contains correlations making it possible to calculate the medium data depending on the pressure and temperature. The density, vapour pressure, enthalpy, flashing data, and the state of aggregation, for example, will be determined automatically.
Missing data will be estimated using approximation methods. The medium drop-down list displays the frequently/recently used media only. To select a medium from the complete list of media and to view a graphical representation of the medium data (isobar), a media explorer can be started from the sizing program directly.

Diagrams:
SAMSON Valve Sizing version 4.5 contains diagram functions for graphical analysis of the sizing:
*Valve characteristic: If the combination of valve type, nominal size and cv-value is present in the database, the at SAMSON R&D department measured valve characteristic will be displayed. If there is no data available, the theoretical characteristic in dependence of the rangeability will be calculated and displayed.

*Pressure-temperature diagram: The pressure-temperature diagram for the selected body material and pressure ratings can be shown. 
This diagram is also utilzed by the program, when the user selects a body material and/ or pressure ratings. Entrees in the drop-down list, which are not allowed according to the pressure-temperature diagram (with respect to the entered process data) are "greyed-out". When a material name is typed in manually, a list with materials which are similar to the entered text and included in the database, appears.

*Media explorer: The media explorer shows the isobars (=graphs at constant pressure)  for the selected medium.

Other new features of the SAMSON Valve Sizing Program version 4.5 include:
*Search function in the project view: The popup-menu for the table columns (right-click the column headers) contains a search menu. An alphabetical list with the complete data of the project for this item will be desplayed. In this way it is possible to search for a certain tag number, or to determine the highest sound pressure level of a project.

*New units for pressure and flow rate, (e.g. MPa and kg/s). Attention: When using the new units in a position, the file is not compatible with former version of the valve sizing program.

*Material for inner parts can be entered.

*New calculation norm for sound pressure calculation EN 60534 8-3 and 8-4 (select "DIN IEC" as calculation norm). The valve factor "xFmr" replaces the former kc-value.

*In the input window for pipe data the pressure ratings / SCHEDULE can be selected. The internal diameter and the wall thickness of the pipe will be determined automatically and will be utilized for the sound pressure calculation.
