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.

NOTICE Material damage due to mineral oils! Mineral oil products cause lasting damage to seals made of EPDM, whereby the sealant properties get lost. We do not assume liability nor provide warranty for damage to property resulting from sealants damaged in this way. - It is imperative to avoid that the EPDM sealing elements of the unit get in contact with substances containing mineral oils. - Use a lubricant based on silicone or polyalkylene and free from mineral oils, such as Unisilikon L250L and Syntheso Glep 1 of the Klüber company or a silicone spray.
