For correct and accurate control functioning, solenoid control valves must be configured and selected according to their special purpose. The most important parameters for selecting a solenoid control valve are, on one hand, the Kv value (given in cubic meters per hour) and, on the other hand, the application’s pressure range.
The lower the valve’s orifice or the stronger the coil, the higher the pressure the valve can shut-off. The highest Kv value needed is calculated on the basis of the following parameters:
Valve inlet pressure
Valve outlet pressure
The fluid’s density
Maximum flow rate required
The fluid’s temperature.
On the basis of the calculated Kv value and the pressure range of the planned application, a correspondingly appropriate valve type and its required orifice can be determined.
