Abstract (en)
[origin: EP2514977A2] The hydraulic control block has a safe fluid path provided in a basic block, where the safe fluid path consists of a pressure chamber port, a high-holding valve (4) and a directional valve (10). The high-holding valve is connected to a terminal for the pressure chamber port of a hydraulic press load, where a downstream of the directional valve from the pressure chamber port is connected to the high-holding valve. A speed valve (28) is arranged in or on the basic block, where the speed valve is arranged between the directional valve and a tank port.
