Illustr. 5.1 Connection identification
The ball valve connector block features an additional
“Flypass” flushing device for the supply pipes:
The Oventrop “Flypass” flushing device is used for
the isolation and flushing of the supply and return
pipe installed in the flow direction in front of the device
or of the succeeding sections of the system. It can
be converted to bypass operation. The straight bores
of the three-way balls and thus their position are
displayed by the shape of the handles and the printed
bars. The flushing device features two lateral threaded
ports G
