Description

The pressure regulator DNOVA PRB is designed to automatically maintain the specified pressure of the working medium in the pipeline to the regulator (in the direction of the working medium). The regulator valve is normally closed when there is no pressure. When the pressure rises to the regulator, the valve opens. In an individual heating point, the pressure regulator DNOVA PRB is installed on the return pipeline of the heating network to stabilize the pressure, as well as to prevent depletion and airing of the dependent heating system at low pressure in the return pipeline of the heating network. Does not work in the absence of flow and in dead-end circuits.
