Function of a hydraulic switch:
When one or more heat generators (with their own pumps) and one or more consumer circuits (with their own distributor pumps) are installed simultaneously in one system, hydraulic switches are used.
Under these operating conditions, the pumps are able to influence each other, which can cause undesired changes in the throughput and discharge head. Using hydraulic switches makes it possible to hydraulically decouple individual circuits from one another so that they can be operated independently.
