## What is Frese Valves?

The Frese Valves app for dynamic flow control is a handy tool for calculations in the field. The Presetting and Sizing Tool helps you to specify the correct output settings, min. ΔP and the required valve dimension per installation.

It also contains a Commissioning Tool which eliminates the need for complex tables and Kv-values. All you need is your phone and a manometer. Just input the valve dimension, pre-set value and the measured differential pressure, and the app will tell you how to set the valve for the optimal output performance.

The tools are intuitive and easy to use and works offline as well as online.

The app can be preset for the following languages: Danish, English, German, Russian, French, Turkish and Chinese.
