Accuracy: ± 10 %. Flow rates: 0,085–11,0 m3/h.
PATENT
Technical data
Maximum percentage of glycol:
50 %
Medium:
water, glycol solutions
Material:
dezincification resistant brass DR
Range △p:
15–200 kPa
Medium temperature range:
-20–100 °C

25 bar
Note
Minimum differential pressure required
This is given by the sum of two values:
- the minimum working Δp of the AUTOFLOW cartridge;
- the Δp required for the nominal flow rate to pass through the valve body. This value can be determined on the basis of the values of Kv shown above referring to the valve body.
Pump head H = Δpcircuit + Δprequise
