  • Gasbreaker | Continental Industries

    EFVs are similar to electrical circuit breakers that trip when electrical current exceeds design limits. They automatically trip when gas flow to a private residence or commercial facility exceeds design limits. This would be the case if a gas service line were to rupture because of ground movement, natural disasters or third party damage.
