Flat-Face Quick-Disconnect Coupling

Non-spill, robust and safe for any application
DBG series, DN 4 to 65
More than 500,000 coupling cycles
Most cost-effective of plain, low-alloy stainless steel

The flat-face sealing design enables non-spill disconnect and inclusion-free coupling operations.

  • Temperatures ranging between -80°C and +325°C
  • Single-hand operation
  • Non-spill disconnection: No environmental damage or hazards to persons due to spilled liquid or exiting gas
  • Inclusion-free coupling operation: no ingress of air or dirt into the piping system
  • CIP capability (Cleaning-in-Place): inline cleaning without product residues
  • Seal replacement at the socket with coupling still in place
  • All types of connection: numerous thread types, hose nipples, flanges, special connections
  • Stainless steel, Hastelloy®, titanium
  • Special types:
    • with hose breaking safeguard
    • with electronic identification system
    • with mechanical pin coding
    • with handles
  • Ready-to-install couplings for docking systems
  • Series products available from stock
