Updates
- posted 3. February 2024 - 13:27

The new version CONVAL® 12 is now available for download.

SOFTWARE LEASE OPTION – CONVAL 365

  • Direct availability of new functions that would otherwise only be rolled out with a release upgrade
  • Update of the supported calculation standards to the most recent version
  • Guarantee of compatibility with the latest Windows versions
  • Continuous updates for quality assurance and bug fixing

EXTENDED LICENSING MODELS

CONVAL supports different licensing variants:

  • Network licenses, which are installed on any workstation or server in your company, and which manage the number of simultaneous users of CONVAL. The installation of the actual calculation software can be done locally on the client or on a network share.
  • Personal licenses, which are provided by F.I.R.S.T. GmbH in the cloud and are bound to a named user. These licenses can be checked out temporarily so that work is still possible even without an Internet connection.

THE NEW USER INTERFACE

  • Clear, contrast-optimized calculation forms based on popular office programs
  • Input pane with variable width for optimum use of the screen width
  • Dynamic fading in and out of parameter captions in multi-column input mask when width is changed
  • Improved scaling support for high-resolution screens
  • Language support for English, Chinese, German, and Russian

ENHANCEMENTS AND IMPROVEMENTS AT RELEASE START

General

  • Revised help system
  • Setting option for the font of tables for the printout

Control Valves

  • Minor improvements and fixes for stability issues
  • CONVAL now also supports valves of the "Dilating Disk" type (valves with an iris shutter-like mechanism).
  • Improved calculation of fluid conditions in the Vena Contracta of multi-stage valves
  • More accurate sound calculation for multi-stage valves if the data of the last stage is not known
  • Improved recommendation for the optimum Cv100 value when several operating points are given
  • Display of flow velocities in the upstream and downstream pipe for all operating points
  • When printing out calculations with diaphragm valves, the valve stroke is not displayed

Actuated Valves

  • Adaptation to the recently issued version of ISO 5115 " Industrial valves - Part-turn valve actuation" (11/2023)

Differential Pressure Flow Elements

  • The calculation of differential pressure flow elements now supports the input of up to three operating points. The names of the operating points can be customized.
  • For concentric orifices, in addition to the pressure tapping points defined in the standards, the distances between the pressure tapping points can optionally be entered freely.
  • Improved design when using the calculation reference "C and ε with 2/3 sqm" by displaying both operating states
  • Calculation of the permanent pressure loss Δϖ for Venturi tubes
  • Improved support of the extended uncertainty calculation in tables and graphs
  • Numerous other minor improvements

Restriction Orifices

  • Minor improvements and correction of stability issues in multi-hole orifice calculation
  • Table view of individual orifices in multi-stage arrangements with more detailed information
  • Display of inlet and outlet flow velocities

Pressure Relief Valves

  • Minor improvements and fixes for stability issues
  • Calculation of the property data in the outlet of the safety valve, including the calculation of the mass vapor content for flashing liquids.
  • Determination of the mass flow to be discharged in the event of thermal expansion in blocked heat exchangers, pipelines, and vessels (thermal relief valves)
  • Determination of the maximum pressure of the blocked pipeline in the event of thermal expansion in pipelines
  • Calculation of the banking-up pressure at the valve outlet with supercritical gas flow
  • Calculation of the discharge function Ψ and Discharge power Φ for compressible flow
  • Graphic display of the corrections for the discharge coefficient for back pressure and lift stop
  • Calculation of the steam pressure coefficient for steam according to ISO 4126-7
  • Improved calculation of two-phase flow pressure relief valves
  • Display of the maximum mass flow rate (maximum mass flow rate = certified mass flow rate / 0.9)
  • Calculation of pipe data (pressure losses, reaction forces, etc.) optionally with the required mass flow rate instead of the maximum mass flow rate
  • Improved support of temperature-dependent curves for the maximum set pressure
  • Improved calculation of safety valves according to API 526 (08/2023)

Thermowells

  • Thermowell calculation now supports input of up to three operating points. The names of the operating points can be customized.
  • Pass/Fail analysis of dimensions, frequencies, and stress limits for up to three operating points
  • Stress analysis can now show the dependence of stress limits on frequency ratio, flow velocity, and now flow rate.

Tank Depressurization

  • Minor improvements and fixes for stability issues
  • Display of flow velocity at valve outlet

Rupture Discs

  • Improved calculation of two-phase flow rupture discs

Pipe Wall Thickness

  •  Pipe wall thickness calculation according to ASME B31.3

Substance Database

  • Numerous viscous oils have been added to the substance database.
  • Improved calculation of mixtures of liquids and gases
  • Calculation of isothermal compressibility χ for media from the Thermodynamics module

License Management

  • Temporary check-out and check-in of network and named user licenses so you can continue to work without a net-work connection.
  • Optimized settings to make it easier to find available licenses
