DILO couplings and valves

C4/C5 series as safe connections to SF6-free gas compartments

For decades, DILO couplings and valves have proven themselves as safe connections in SF6-filled gas compartments. We also offer appropriate connections for connecting
SF6-free switchgear or electrical equipment, which are essential for safe and emission-free gas handling.

DILO couplings C4: for gas mixtures based on 3MTM NovecTM 4710
DILO couplings C5: for gas mixtures based on 3MTM NovecTM 5110

Advantages of application at a glance

  • Self-closing coupling system for DN8 and DN20
  • Pressure- and vacuum-tight even when coupling and uncoupling
  • Leak rate equal to or less than 1x10-8 mbar l/s
  • Permanent tightness even when frequently connected and disconnected
  • Direct connection to DILO service carts C4/C5 without adapters
  • DILO threads adapted to the basic gas to prevent wrong connection
  • Available in different materials even for outdoor switchgear
