These days many turbine engines have internal pumps making the use of cut-off fuel valves of the Festo type risky. They should normally be placed only on the pressurized side of the circuit. One can use the metal ball valve JetCat valves but they only come in the 4mm size. These are too restrictive for larger than 100 N sized engines.

I have looked but cannot find an equivalent valve for fuel that is appropriate for larger engines. A barbed 6mm fuel safe and an 8mm size ball valve are needed to cover most larger engines. Anybody have a source for these?

Been using festo shutoff valves on my RXI engines for several years now. Never had any air in-leakage.
