Product details: FF manual balancing valve 2 3/4 pressure ports - Manual Balancing - Hydraulic balancing makes it possible to compensate for the unequal distribution of flow rates (pressure losses) in an installation caused by the geometry of the circuits (height of the floors, distance from the main inlet, elbows?). It thus ensures uniform comfort at any location in a building, and optimizes energy or water consumption (sanitary applications). Balancing is based on the placement of valves at strategic locations in the circuit in order to control the flow. It is essential if the installation is subject to variable flow rates. It adjusts the flow rate necessary for each of the branches or devices allowing them to deliver the power for which they were calculated.
