NT-RS201   Run-Stop solenoid valve.

This is a Dual Spool - 2 Position, 3-Way Valve. Used for, switch controlled main engine shut off (run-stop), afterburner main fuel and streak control applications.
Dual spools - Reduces the likelihood of failure due to a single spool sticking open. This is required by many sanctioning bodies.
For turbine main fuel, the NT-RS201 simplifies the throttle system. The power lever can be left at the ground idle position, keeping the stop-cock position in reserve for emergency shut down.
Provides easy way to purge and circulate the fuel system. Helpful when blending fuel additives.
Can be used as a fuel selector valve for Bio-Diesel powered vehicles.
I have found this to be the trick set-up for turbine run-stop control. The spools have a “soft shift” feature that won't "dead-head" the FCU. The drain to tank port starts to open before the flow divider port closes.
I would not trust a simple 2-Way "on-off" valve that just opens a line to tank and relies on the anti-piddle valve in your flow divider to stop fuel flow to the engine. Nor would I use one to simply block the fuel flow with no return to tank. Get the positive-acting NT-RS201” - Mark
