With my Jetcentral turbines I've been used to receive a mechanical fuel shutoff valve besides the fuel solenoid.

Now that I received two (2) SPT 5 turboprops from Jetcat, I was looking for this valves but they are not included. Looking at the install diagram, they are not even shown.

Are you guys including additional shutoff valves for your Jetcats ? What happens if your fuel solenoid fails and remains open while you fuel your turbine ? You can have a hot start.....
