VALVE UNIT HAVING INDIVIDUAL PRESSURE SCALE AND LOAD-LOWERING VALVE

摘要

The present subject matter in general relates to a valve unit for supplying pressure medium to a hydraulic load (2) with a housing (58). The valve unit comprises a directional valve (8) arranged on the housing (58). The directional valve (8) comprises an adjustable inflow measuring diaphragm (10, 12) and a directional part (14, 16). The valve unit further includes an individual pressure regulator (18) arranged on the housing (58). The individual pressure regulator (18) is assigned to one of the inflow measuring diaphragm (10, 12). Further, a load-lowering valve (44, 46) is acted upon by a pilot pressure in an opening direction in the direction of the hydraulic load (2). A non-return valve (48, 50) is connected in parallel to the hydraulic load (2). According to the present subject matter, the pilot pressure is tapped in a channel (20) between the pressure regulator (18) and the directional part (14, 16).
