Valve Kv Calculator

Calculation of valve authority and kvs coefficient

enter the valve authority (default set to 0.5); circuit resistance where the valve will be installed (without this valve's resistance) and enter the flow in m3/h or dm3/s for the program to calculate the required Kv value of the valve and pressure drop across this valve in bars.

Recommended authority is 0.3 - 0.7. The maximum authority value that can be entered for calculations is 0.99

In the second calculation type, select a valve with the appropriate kvs and flow in m3/h or dm3/s for the program to calculate the pressure drop on the actual valve in bars and kilopascals

Additionally, the application will calculate the real valve authority by comparing the actual valve pressure drop to the installation resistances

When entering flow in m3/h, the program will convert it to dm3/s and vice versa.
