AIR SHUT OFF VALVES SERIES

Air shut off valves for internal combustion engines
The hydrocarbons which are potentially present in the atmosphere can become a real problem when attempting to make a controlled stop of an internal combustion engine.
These hydrocarbons may be sucked in by the engine air intake system producing acceleration and loss of speed control with the subsequent risk of explosion or deflagration.
The ordinary stopping methods (for example, shutting down of the fuel flow) may be quite useless, leaving the engine running without any possibility of stopping.
The GALI valve allows the automatic closing of the engine’s air intake, increasing safety in places such as offshore or onshore oil platforms, engine rooms, and petrochemical refineries.
