  • SF6 valves couplings – Synergy Power Systems

    When using the DILO coupling system a leak rate of better than 1 x 10-8 mbar l/sec. is achieved corresponding to less than 1 cm³ in 3 years. The DILO seal principle prevents the loss of SF6 gas and moisture from penetrating the SF6 gas system. DILO couplings will eliminate the loss of SF6 gas by incorrect gas handling.
