摘要
A device (1) for piloting by means of a substantially incompressible fluid, comprising a two-way flow control valve (2) which operates along a piloting line (3) and has at least one first port and one second port (4, 5), which are adapted to be connected, respectively, to means (102) for supplying a substantially incompressible fluid under pressure and to a fluid-operated element (107) to be piloted by means of the piloting line (3) and choke means (6) arranged in parallel to the flow control valve (2) along a bypass duct (7) which is closed in a loop on the piloting line (3), the flow control valve (2) being actuated for closing by the pressure at the second port (5), the calibration pressure value at which the flow control valve (2) closes being at most equal to the actuation pressure value of the element (107) to be piloted.
