Air Intake Valves

If flammable gas or vapour is drawn into the air intake of a diesel engine, it acts as an additional ungoverned fuel supply. This may result in uncontrolled engine overspeed followed by dangerous mechanical failure or flash back through the intake and the ignition of the surrounding gas or vapour cloud.

Once a flammable mixture is being drawn into the engine intake it may not be possible to stop the engine by closing down the fuel supply. For this reason an air intake valve must be fitted to ensure a guaranteed rapid and safe engine shutdown.

The Chawlyn shut down valves have metal to metal seals, different size options depending on power and physical size of the air intake and hazardous area options are available.
