Equipment for modular sytem DN 20

Overflow set DN 20 (

3⁄4")

For hydronic heating installations with standard circulation pumps and thermostatic or

zone valves.

The PAW differential pressure overflow valve reduces noises due to circulation and keeps

the pump pressure constant, even when the flow in the radiators is reduced (particularly

when thermostatic valves are used).

The valve controls the flow rate in proportion to the thermostatic or zone valves.

The return temperature is increased as soon as the valve opens.

For weather compensated control we recommend to mount the sensor to the flow line

directly behind the circulation pump. The higher return temperature guarantees that the

boiler does not corrode.
