Abstract: A valve for use in a gas turbine. The valve includes at least one valve body, at least first, second and third fluid delivery pipes positioned on the valve body, at least one outlet pipe positioned on the valve body and a rotatable spherical shutter inside the valve body (and including first and second distribution channels formed within the shutter so as to allow the outlet pipe to be selectively connected to one of the delivery pipes during rotation of the shutter.

Abstract: This system for supplying a turbine with liquid fuel comprises a liquid fuel inlet (3), a piping assembly (4) connecting the inlet to the turbine, and draining means for draining at least a portion of the said piping assembly. The draining means comprise water inlet means (9) and a system of controllable valves suitable for injecting water into at least one of the said portions of the piping assembly.
