Functional description

The flow is isolated by a ball inside the ball valve by
turning the handle.
A bypass between the primary supply and return
can be opened with the help of the "Flypass" fitting.
This way, the primary circuit in the flow direction in
front of the fitting can be flushed even if the "Regudis
W-HTE" is not fitted.
