Flat-face quick disconnect coupling 

Flat-face quick disconnect coupling 

Flachdichtende Schnellkupplung Serie DBG

GATHER’s flat-face quick disconnect couplings of the DBG series shut off on both sides and can be operated with one hand. They are designed in such a way that no liquids escape when disconnected and no air pockets enter the pipe system when connected. The design of their internal structure allows inline cleaning CIP (Cleaning in Place).

All components are sufficiently washed around, product adhesions are completely removed. The pressure drop in the quick disconnect coupling is very low, as the flushability is achieved by its inner contour which ensures a favourable flow. All seals are located on the inside, which means increased operational safety.

  • Dry-break, robust and safe for every application

  • DBG series, DN 4 to DN 65

  • Over 500,000 coupling cycles

  • The price cutter made of simple, alloyed steel
