摘要： The object of the invention is a device (100, 200, 200bis, 300, 300bis) for controlling a pilot pressure signal of hydraulic valves (3), for controlling the handling of gravitational loads (M), operating between two pilot lines (108, 109, 208, 209, 308, 309) between said valve (3) and a cylinder (1) adapted to sustain the load (M). The device (100, 200, 200bis, 300, 300bis) is a two-way and two-position valve for the communication between the cylinder stem-side pilot line (5) and the valve-side line (3) and is a valve which can take an open position and a partialized position, or anyway it never takes a closed position. The device (100, 200, 200bis, 300, 300bis) can take a position so that the fluid passage between the pilot lines (108, 109, 208, 209, 308, 309) is never completely closed.
