Requested minimum differential pressure
This is given by the sum of the values:
1. the minimum working Dp of the Autoflow cartridge;
2. the Dp required for the nominal flow to pass through the valve body. This value can be determined on the basis of the values of Kv0,01 shown above referring to the valve body only.
