Automatic balancing valves

- CuZn39 Pb2 hot-forged brass pressure points and plugs, stainless steel spring
- Upstream and downstream pressure measurement sockets for Δp control
- Adjustment accuracy +/- 10% constant over the entire flow range
- Operating range, for cartridges:
► Green, 17 to 200
► Red, 30 to 400 kPa, DN 15-20 grey cursor
- Below the minimum differential pressure (Δp mini), the valve acts as a fixed
orifice
- In the range between Δp min and Δp max, the flow is kept constant. Beyond,
the flow increases again
- Factory settings :
► 4.0 for cPIA
► 3.5 for cPIA
4.4.6

Ultrasonic sensor for energy metering

- Nominal flow : 1,5m3/h
- Maxmimum pressure : 16 bar
- Minimal flow : 15l/h
- Temperature range : 0/90°C
- In/out ΔT° range : 2/90°C
- Straight lengths recommended before the sensor: 110mm
EUREVIA declines any responsibility on hydraulic equipment damage if it's due to hydraulic network design
problems or to human errors during commissioning
