| KVS - valve | from 0.008 to 925 m3/h |
| Leakage | max. 0.01%Kvs |
Calculation of the Kv value of the valve is done according to DIN IEC 534. Questionnaire contains the parameters of the valve needed for calculation.
For a simplified calculation of control valves generally known formulas given in the table can be used.
| p1 | Inlet pressure |
| p2 | Outlet presure |
| H | Stroke |
| Q | Flow u m3/h |
| W | Flow u Kg/m3 |
| ρ | Density Kg/m3 (Liquid) |
| ρ1 | Inlet density Kg/m3 (For gas and steam) |
| t1 | Inlet temperature °C |
After the Kv value is calculated, the Kvs is chosen - value is in the valve characteristic diagrams (linear and straight percentage).
If the real parameters were used in calculation, in most cases will be ≈ 0,7 do 0,8 • Kvs.
