sf6 gas 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 Sulfr hexafluoride gas and moisture from penetrating the Sulfr hexafluoride gas system. DILO couplings will eliminate the loss of sf6 gas gas by incorrect gas handling.

SF VALVES AND COUPLINGS - World Leader in Sulfr hexafluoride Maintenance

DILO couplings allow a connection to be made by simply screwing the two coupling parts together. Before the metal-to-metal seal closes, the pressure and vacuum tight coupling is sealed inside by means of an O-ring. When loosening the coupling parts again, the same O-ring prevents gas loss whilst the self seal valves close. Advantages of application
