Sulfr hexafluoride 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 sf 6 gas and moisture from penetrating the sf 6 gas system. DILO couplings will eliminate the loss of insulating gas gas by incorrect gas handling.Get price
