The SAMSON Valve Sizing Program Version 2.0

The SAMSON Valve Sizing Program

SAMSON Valve Sizing Help should provide you with a general overview of the possible applications offered by this program.

Control valves and the required actuator for a particular item can basically be specified with three operational cases (minimum operational case, maximum operational case and standard) using the program. Furthermore, the corresponding noise level is calculated according to the selected calculation standard. The standard VDMA 24422 in the 1979 version as well as in the new 1989 version, for gases and vapors DIN IEC 534 Part 8-3 and finally a special SAMSON Standard are available for this.

The minimum required flow coefficient and the minimum required nominal size are calculated for valve sizing with the so-called header, process and medium data for each operational case according to DIN IEC 534. The Kvs value, the nominal size, the nominal pressure level and other valve data (valve data part 1 and valve data part 2) are selected from the maximum values of these results and from input data from Database. A general valve is selected here and not a special SAMSON product. The possibility of a special SAMSON valve being suggested in which, for example, nominal size, nominal pressure level and particular materials are observed in accordance with the SAMSON catalog, will only be available in a later version of this program under the Database/SAMSON option.

The noise level corresponding with the selected calculation standard is then calculated for all operational cases of the valve determined here. The valve factors (valve factors part 1 and valve factors part 2) required for the respective standard are calculated and suggested for a valve from the SAMSON product range corresponding with the selected valve. These valve factors (valve factors part 1 and valve factors part 2) as well as all other data which is required for calculating the noise level, for example, the pipe data, can, however, be changed at any time.

This allows the program to simultaneously provide exact results in conjunction with the SAMSON calculation standard for special SAMSON products and also to be used for any other valves with any valve factors (valve factors part 1 and valve factors part 2).

The maximum actuator force required for the specified valve is calculated for actuator sizing. An actuator is then specified for the required actuator force and the valve selected. The actuator results are then calculated for this actuator.
In contrast to the valve, a SAMSON product database is contained in the program so a real SAMSON actuator is suggested.

Both valve data and factors and also actuator data which is suggested by the program can be changed at any time.

To make working with the program easier and to provide flexible application possibilities, various settings, options and input aids are available. In this way you can, for example, chose between different languages, convert the technical units, etc. You will find more information on this in the Help topics for the Main menu, on the toolbar buttons and the status bar.

Important: Despite all efforts to avoid program errors, this version could still contain bugs. Should you discover any bugs or have any suggestions for improvement, please write to:
