Abstract
An arrangement for managing a liquid medium, such as water, combines a pressure-reducing valve with two backflow prevention valves. Both the pressure-reducing valve and the two backflow prevention valves may be integrated into a common housing, specifically with both backflow prevention valves in an inlet chamber of the housing, wherein the inlet chamber and an outlet chamber of the housing are either fluidly coupled or isolated from one another by the pressure-reducing valve depending on the outlet chamber pressure prevailing in the outlet chamber. In some instances, a manually actuatable shut-off valve may be integrated into the housing. The manually actuatable shut-off valve may selectively keep the pressure-reducing valve in a closed position or allow the automatic opening and closing of the pressure-reducing valve depending on the outlet chamber pressure prevailing in the outlet chamber.
