    Pilot controlHydraulics & Mining technology

    Pilot control systems are used to control hydraulic cylinders in underground mechanical supporting structures.
    These control units can actuate between 2 and 20 functions, each of which is designed specific to customer requirements.
    The main control unit consists of 3/2-way valve cartridges DN10, DN12 or DN20 plus high pressure and return connections. The control pressure is supplied to the main control cartridges via the multi-hose.

    The pilot valves are mounted on the pilot control unit, with which both main and auxiliary functions can be driven - all functions specific to customer requirements. The pilot valves function according to the dead man principle: the cylinder ceases to move when the lever is released. The pilot control unit is linked to the main control block via the multi-hose.
