Abstract: An air intake shut-off valve comprising a valve housing, a pivot shaft, an actuator shaft, a valve disk, a solenoid having a trip rod, a service port cover, an air inlet and an air outlet is disclosed. A first end of the pivot shaft has an “L” shaped notch in the first end and a second end attaches to the valve disk. The pivot shaft rotates about the actuator shaft from a first position to a second position. A first end of the trip rod extends through the valve housing and engages the “L” shaped notch in the first position and the first end of the trip rod disengages from the “L” shaped notch in the second position. The valve disk covers the air outlet in the second position. A method of the using the air intake shut-off valve is also discussed.
