A circuit () for draining at least one combustible fluid for a cavity of a turbine includes a drain () in fluidic communication with the at least one cavity, and a first isolation valve () and a second isolation valve () defining between them an isolation cavity (C) of a portion of the drain. A discharge line () is in fluidic communication with the isolation cavity (C) to allow the discharge of air out of the isolation cavity (C). A supply line () supplies pressurized fluid to the isolation cavity (C), and a supply valve () is arranged in the supply line () for regulating the supply of the isolation cavity (C) with pressurized fluid. A discharge valve () is arranged in the discharge line () for regulating the discharge of the gases out of the isolation cavity (C), and a device () is provided for determining a failure of the drainage circuit ().

A multi-way valve includes an outer casing provided with an internal cavity, at least one input to the cavity, at least one output from the cavity, the at least one input having sealing means, and an actuator adapted to cause the opening of the sealing means of the inputs. A cross-section of the actuator is smaller than a cross-section of the inner cavity.
