Connection under pressure

Special series DBG-CUP, DN 12 to 25
Non-spilling, robust and save for every application
CUP SYSTEM® – Connection Under Pressure
Unique in its class

The DBG-CUP series features tube-to-hose connection
with both components pressurized without the need
to first release the pressure. This is due to the merits
offered by the unique CUP SYSTEM®. The design of the
CUP valve makes sure the system pressure has minimal
influence on the coupling force.

Flat-face design allows non-splling disconnection and inclusion-free engagement.
