[103] 3/2-way valves as diverter
In addition to their
application as final control elements, 3/2-way valves can also be
used as diverters. In this case, port T is connected to a further
device, to which a switch-over can then be made. The part circuit
diagrams show the facility to switch between the flow control
valves with different settings and between heating and
cooling.
The circuit symbol is drawn reversed to simplify the representation of the circuit diagram.
