Abstract (en)
[origin: WO2009127349A1] The invention relates to a control arrangement with a pilot aggregate (6) for controlling a control valve (2) comprising a first and a second control chamber (36, 38). The first control chamber (36) is provided for adjusting the control valve (2) in one direction and the second control chamber (38) for adjusting the control valve in the opposite direction. The control chambers (36, 38) are applied each with a pilot pressure of the pilot aggregate (6). Besides the pilot aggregate (5), the control arrangement further comprises a pilot valve (4) for applying a control chamber (36, 38) with an outlet pressure. The supply pressure of the pilot valve (4) is hereby the pilot pressure of the pilot aggregate (6) effective in one of the control chambers (36, 38) and the output pressure of the pilot valve (4) is effective in the other control chamber (36, 38), wherein the output pressure is equal or smaller than the pilot pressure.
