Product Description

Compact automatic flow rate regulator, in line, with high resistance tecnopolymer cartridge.
Flow rates: 0,02–0,06 m3/h - Δp range: 20–200 kPa - Accuracy: ± 15 %.
Flow rates: 0,085–11,0 m3/h - Δp range: 15–200 kPa - Accuracy: ± 10 %.
PATENT

Technical data

Material: brass
Medium: water, glycol solutions
Maximum percentage of glycol: 50 %
Medium temperature range: 0–100 °C
Maximum working pressure: 16 bar

Note

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
