AUTOFLOW® - Automatic flow rate regulator with high resistance polymer cartridge

Description: 

Automatic flow rate regulator.
Dezincification resistant alloy body.
AUTOFLOW® cartridge:
1/2”–1 1/4” in high resistance polymer,
1 1/2” - 2” in high resistance polymer and stainless steel.
Max. working pressure: 25 bar.
Temperature range: -20–100 °C.
Max. percentage of glycol: 50 %.
Δp range: 15–200 kPa.
Flow rates: 0,085–11,0 m3/h.
Accuracy: ±10%.

Fitted for connection of pressure ports and drain valve.

Minimum differential pressure required
This is given by the sum of two values:
1. the minimum working Δp of the AUTOFLOW® cartridge;
2. 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
