DILO SF6 valves and couplings

The perfect connection to gas compartments

Are you looking for pressure and vacuum tight valves and couplings for SF6 gas use? DILO is the right choice! We offer the largest range of products worldwide. Whether for medium voltage switchgear, high voltage switchgear or gas-insulated lines (GIL) our products always meet your requirements.

The DILO self-sealing principle prevents the loss of SF6 gas and inhibits moisture from penetrating the SF6 gas system. DILO's valves and couplings will eliminate the loss of SF6 gas by incorrect gas handling. Thanks to their reliability, quality, and durability, DILO valves and couplings are the world's most widely used connecting system for SF6 switchgear.
