DU differential pressure relief valve with angle setting

DIFFERENTIAL PRESSURE RELIEF VALVE AFRISO 3/4

Use

DU differential pressure relief valves are used in closed heating systems to maintain a constant available pressure in the system. Excess heating medium at increasing pressure, e.g. with closed radiator valves, flows into the return line. Bleed valves also contribute to reducing noise in the installation and maintaining a constant minimum flow through the pump and heat source.

Assembly

The differential pressure relief valve shall be mounted on the bypass between the supply and return of the installation. The flow of the medium through the valve must be consistent with the arrow placed on the body.
