Positive Air Shutdown (PAS)
Engine Shut Off
Industries such as mining, oil refinery and forestry require
some vehilles to have an emergency engine shutdown in place
- the most effective method for this is to cut the air supply
to the engine ensuring fuel ignition to cease. With BD's emergncy
shutdown system, a butterfly valve is placed inline in the air
intake system and when activated, a heavy duty electical solenoid
trips a locked safety cam causing the engine to shutdown within
seconds, resulting in a safe effective shutdown.

& Stainless Steel Components
Emergency Engine Shutdown butterfly valve design simplifies
the number of parts and reduces the overall size as compared
to competitive units and uses aluminum and stainless componenets
plus weatherproof electrical connectors to prevent corrosion.
Easy installation with bead boot locks - no need for welding.
Standard applications include over-speed electronics and CAC
pipes included for some vehicles.
you need an emergency engine shutdown system, then BD has the
solution that is hard to PASs up. We use an in-line butterfly
valve which is activated by a heavy duty electrical solenoid
to shut an engine down within seconds.
exclusive locking lever prevents closures from vibration and
the electrical solenoid must be engaged in order to close the
innovative bead boot lock design to keep the included rubber
boots securely in place under high boost pressures — easy
to install with no welding required.
butterfly design only adds 3-inches of height on top of the
pipe as compared to guillotine style valves that can double
that! Boots and clamps included in the kit.
