DILO couplings and valves

Emission-Free connections to SF₆-free gas compartments for C4/C5 series

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

DILO couplings C4: for gas mixtures based on C4-FN
DILO couplings C5: for gas mixtures based on C5-FK

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
