Standard or flexible design
For installations where all three or four pipes
are of the same DN, and where you do not
expect to change pipe size at a later stage, a
standard combi-cross is recommended.
Flexible combi-crosses are recommended

outlets. Since there is no need for transition
or reduction flanges, installation of a flexible
combi-cross saves time and money.
Full bore centre outlet
The full bore centre outlet allows for insertion
of solid foam pipe cleaning devices, and the
DN100 flange can be used for mounting a
hydrant or as inspection access point to the
water stream. The centre outlet lid is mounted
with standard bolts and nuts thus avoiding
threads directly in the casting. An O-ring placed
in a recess provides optimal tightness between
the centre part and the lid.
Safe anchoring
The AVK combi-cross is designed to meet
stringent safety requirements. Even when valves
are disconnected and removed from the centre
part, the anchoring remains unaffected. This
provides maximum safety for the staff working
in the concrete chamber, since the forces from
pressure and pipe movement are directed
through the fixating lugs and into the standard
concrete foundation.
