F.I.R.S.T. CONVAL 2026 for PC — Free Download & Install on Windows 10/11

F.I.R.S.T. CONVAL 2026 is control-valve sizing software for Windows from F.I.R.S.T. GmbH, a German engineering software company. It calculates and selects control valves for liquids, gases, steam and two-phase flow, helping engineers choose a valve that fits the process conditions. If you work in plant engineering, process design or maintenance and need to size a control valve correctly, CONVAL is a specialist tool for that exact job. This guide explains what it does, its main features and system requirements, and how to download and install it safely from the official F.I.R.S.T. website.

1. What Is F.I.R.S.T. CONVAL 2026?

F.I.R.S.T. CONVAL 2026 is the current version of CONVAL, the control-valve sizing program from F.I.R.S.T. GmbH. A control valve regulates the flow of a liquid or gas in a pipe, and choosing the wrong size can cause poor control, noise, vibration or damage to the valve. CONVAL performs the sizing calculation according to recognised standards, using the flow rate, pressures, temperatures and fluid properties you enter. It is aimed at process engineers, plant designers and valve specialists who need a reliable, repeatable calculation and a clear report to document the result. The program is available as a Windows application and as a cloud version, known as CONVAL SaaS, which runs in a web browser.

2. Key Features of F.I.R.S.T. CONVAL 2026

Control-valve sizing: Size control valves for liquids, gases, steam and two-phase flow, with results based on recognised sizing standards.
Flow coefficient calculation: Calculate the required Cv and Kv values for the valve from your process data.
Noise prediction: Estimate the noise a valve will produce, so loud or unsuitable selections can be avoided.
Cavitation and flashing checks: Check whether cavitation or flashing is likely at the valve, and choose a valve that handles it.
Actuator sizing: Size the actuator that drives the valve, so the valve opens and closes reliably under process conditions.
Valve database: Work with a database of valve types and sizes to compare possible selections for the same duty.
Calculation reports: Produce a clear, printable report of the sizing calculation for documentation and review.
Cloud version: Use CONVAL SaaS in a web browser when you prefer not to install software on your PC.

6. How to Use F.I.R.S.T. CONVAL 2026: Your First Sizing Calculation

Your first task is to size a valve for a simple case. Open CONVAL and create a new sizing case, then enter the fluid type — water, for example — together with the flow rate, the inlet and outlet pressures, and the temperature. Choose the valve type you want to check, such as a globe valve, and run the calculation. CONVAL returns the required Cv or Kv value and suggests suitable valve sizes from its database. Review the noise and cavitation results, and adjust the valve size or type if the results show a problem. When the selection looks right, save the case and export the calculation report for your records.

7. Is F.I.R.S.T. CONVAL 2026 Free? Price Explained

F.I.R.S.T. CONVAL 2026 is commercial engineering software, but you can try it free.
