The Butterfly Air Intake Shutoff Valve provides emergency shutdown of a diesel engine. When the positive spring actuated valve closes, it starves
the diesel engine of air and combustible vapor ingested through the air intake line.

Operating logic:
The diesel engine speed is governed by
controlling the amount of fuel fed to the engine
through its fuel system and internal speed
governor. If a flammable, material is drawn
into the air intake system of a diesel engine it
acts as an additional ungoverned fuel supply.
This additional fuel source can cause the
diesel engine to accelerate or over speed out
of control. This condition is referred to as
diesel engine runaway. The result of a diesel
engine runaway can range from engine
damage to a catastrophic explosion.
Operating the normal shutdown control will
only turn off the engine’s diesel fuel source.
Once the external flammable gas or vapor is
being drawn into the engine intake, it may not
be possible to stop the engine using the
normal engine shutdown. The most effective
way of shutting down a runaway diesel engine
is with an automatic air intake shutoff valve.
An air intake shutoff valve completely blocks
the engine air intake pipe, cutting off both the
external fuel source and the air required to
keep the engine running
• SVX Energize To Run Valve
• Actuation “fail safe”:
The valves are equipped with
2-coil solenoids. The “Pull”
coil is used to open the valve
when power is initially
applied. The second coil is
the “Hold” coil which is used
to hold the valve open in run
position as long as power is
supplied. When power is cut
off for any reason such as the
detection of an engine
overspeed condition the valve
will close.
• The Valves are also powered
and controlled by Emergency
stop button (installed in the
genset)
• Designed for -40°C to 150°C
(-40°F to 300°F) intake air
• Major components
manufactured of aluminum,
brass, and stainless steel
• Corrosion resistant body
components.
