AUTOFLOW® - Automatic flow rate regulator with high resistance polymer cartridge and ball valve
Description:
Combination automatic flow rate regulator and ball valve.
Brass body.
High resistance polymer AUTOFLOW® cartridge.
Max. working pressure: 16 bar
Temperature range: 0–100°C
Max. percentage of glycol: 50%
Δp range: 15–200 kPa
Flow rates: 0,12–5,0 m3/h
Accuracy: ±10%

Fitted for connection of pressure ports and drain valve.

If the pipework is insulated, the lever can be replaced with an extended
handle (117 series on page 182).

Patent application No. MI2004A001549.

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.
