I wenbt through the air injection system and did not find the terminology ofr a, "Shot off valve". However there is a check valve and a pulsed air valve in the air injection system. I gave you diagrams of what they look like and they should be easy to find as you can trace using the system diagram and the pulse valve is located near the top of engine and is large and shown in diagram.
Please consider a to help us answer more questions.
