Abstract (en)

[origin: EP0558976A1] The invention relates to a safety valve (10) for pressure-medium-actuated working members, e.g. double-acting cylinders of presses, with two valves which can be actuated via one pilot valve (58, 60) each, one reservoir chamber (44, 46) each being provided for the admission of pressure medium to the two valves. So that the lines from the pilot valves (58, 60) to the storage chambers (44, 46) can be kept short and so that less lines are needed, a directional control valve (80, 82) is connected between each reservoir chamber (44, 46) and each pilot valve (58, 60). <IMAGE>
