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 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 oil platforms, engine rooms on-board ships and on land, and petrochemical refineries and plants.







On installations with diesel engines in hazardous areas, we can supply GALI range of air shut off valves for the engine protection in ATEX version.

GALI ATEX valves ensure the immediate stop of the engine, designed under the requirements of the ATEX directive. The electrical continuity between the different parts of the engine.

We ensure a very reduced installation space on the engine, free maintenance and high reliability.

We can provide special cable glands and cable sizes upon request.

We can provide different type of flanges for all kind of engines to guarantee a correct and easy installation on the engine.

Do not hesitate to contact us with any questions, our technical department together with GALI engineers will be happy to provide more information and calculation to find out what solution is best for your needs.
