Engine Air Intake Shut Down Valves

If flammable gas or vapor is drawn into the intake of a diesel engine it acts as an additional ungoverned fuel supply. When this occurs the only certain way to stop the engine is by the operation of an air intake shut down (shut off) valve. Failure to stop the engine can result in uncontrolled engine overspeed followed by mechanical failure or flash back from the intake resulting in ignition of the surrounding flammable atmosphere.

Chalwyn builds a wide variety of air intake valves which are categorized and presented below. Each link will lead to a separate web page containing additional information and links to download Chalwyn sales and technical brochures.
