CONVAL Service Release 10.5 - Release notes:

The CONVAL Service Release 10.5 provides the following improvements:

Miscellaneous
- Multilingual version (English, French, German, Polish)
- Fixes of stability issues with certain Windows region and language settings
- Fixes of stability issues when exporting calculations
- Several issues with changing the display language have been fixed.
- Improved behavior with occupied network licenses
- Version history of the program and databases during the update check
- Minor improvements and fixes of stability issues
Control Valve
- In some cases, the downstream pressure p2 could no longer be entered after switching off downstream resistor structures.
- When calculating downstream silencers, the minimum plate thickness e,min was not calculated properly.
- Various issues with the selection of body materials for valves from the database have been resolved.
- Revised reliability analysis of valves at flashing conditions
- Incorrect values in the data table of the characteristic curves for two-phase flow in the inlet and input of the individual mass flows have been corrected.
- The export of calculations to the specification sheet according to IEC 60534-7 has been revised.
- Fixed stability issues - also in the database maintenance program - and minor improvements in the help system.
Differential Pressure Flow Element
- Fixed stability issues when creating parameter graphs
- Minor improvements for integrated orifice plates and unspecified differential pressure transmitters
- The expansion factor ε was not calculated for gases with an isentropic exponent ϰ = 1.
- New is the calculation of the permanent pressure loss for wedge flowmeters.
Restriction Orifice Plate
- Revised calculation of minimum plate thickness e,min for choked flow conditions and for multi-hole orifice plates in general. The new calculation method gives more conservative results.
- The outlet temperature t2 may have been incorrectly calculated for gases in the supercritical range.
- Minor improvements in messages and help system
Pressure Relief Valve
- Calculation of valves according to the current edition of API 526 (2017). This replaces the 2002 version.
- In some cases, the back pressure was not calculated if the valve outlet size is smaller than the inlet size.
- Minor improvements and fixes of stability problems
Thermowell
- Message about possible causes if frequency ratio R is too large
- Revised help system with corrected formulas and description of stress analysis diagram.
Pressure Loss
- Minor improvements and fixes of stability issues
Material Data
- Fixing stability problems in the calculation of materials near their limits of use


CONVAL - the software solution for engineers, planners and operators of industrial plants and has extensive calculation options for components and procedures in the process industry. Proven practices according to DIN, VDI, VDMA EN/ISO standards or ISA, ASME, API etc. are used as a basis. This ensures that the correct calculation basis is always available even in international projects.

The largest database of device manufacturers in a software.
CONVAL guarantees a flexible and professional use without having to forego specific manufacturer data due to its absolute independence from device manufacturers. A constantly growing range of control and safety valves, bursting discs, flowmeters and much more ensures a seamless calculation process for your projects. If you still use devices that are not available in CONVAL, it offers an easy way to enter this data. We are also happy to support you with the implementation of your own data in the program.

Calculations with different fluids and materials
The range of available calculations extends from control and safety valves, flowmeters and thermometer protection tubes to pipeline calculations, heat exchangers or pumps.The calculations are always based on an extensive substance database for pure substances as well as mixtures, whose properties can be calculated depending on pressure and temperature. If you require high accuracy, media properties at high pressures or low temperatures, the data can be calculated on the basis of thermodynamic equations of state.


F.I.R.S.T. Gesellschaft für technisch-wissenschaftliche Softwareanwendungen mbH, based in Wermelskirchen, came into being in 1989.

The company's goal is to continuously improve CONVAL, a software product for PCs that was developed by the founding fathers during the years preceding the startup, and to sell it in the international marketplace.

The idea for CONVAL was born in the late seventies and originally realized in the guise of small routines for programmable pocket calculators. Several of the calculation modules that today are integral components of CONVAL existed in a simplified form even then.
