Refuel shut-off valve closing time
Refuel shut-off valve closing time
(OP)
Hi!
I really hope that somebody can help me.
I need to find closing time for refuel shut-off vales (Any. Best of all would be for motor controled ones). Could anyone tell me how to do it or tell me where I can try to find some information.
I have a belive that it is possible to calculate but I heed your help.
Kind regards,
Laura

The actual time will depend on the actual valve and application. Size of the valve, pressure and flow, power source and actuator size all are factors.
..
What would happen to the aircraft if the power fails during a refuel and your valve isn't able to be energized closed? That is the main reason most aircraft have 2 refuel valves in the tank, and either can shut off the flow once the fuel level reaches the maximum depth for that tank. Even if electrical power is interupted.
