A fuel tank valve for connection to a degassing circuit to define a passage for a flow of gas leaving the tank, the valve being characterized by the fact that it has at least one moving member (18; 55) capable of being controlled in displacement to modify the configuration of said valve (1; 42), and by the fact that the valve has a first moving closure element (26; 65) having an orifice (29; 67) and suitable for being moved by the moving member (18; 55) from a first position towards a second position, the transition from the first position to the second position reducing the flow section made available to the flow of gas.
