Abstract
A device for piloting by means of a substantially incompressible fluid, comprising a two-way flow control valve which operates along a piloting line and has at least one first port and one second port, which are adapted to be connected, respectively, to elements for supplying a substantially incompressible fluid under pressure and to a fluid-operated element to be piloted by the piloting line and choke elements arranged in parallel to the flow control valve along a bypass duct which is closed in a loop on the piloting line, the flow control valve being actuated for closing by the pressure at the second port, the calibration pressure value at which the flow control valve closes being at most equal to the actuation pressure value of the element to be piloted.
