The invention concerns a valve arrangement (1) with a high-pressure connection (P), a low-pressure connection (T), at least one control valve (2 to 5), which is accommodated in a control valve module and has at least one working connection (A, B) for a hydraulic consumer (7 to 10), and a safety valve (6), which is accommodated in a safety valve module, and which releases or blocks a passage between the high-pressure connection (P) and the control valves (2 to 5), the control valve module (2 to 5) and the safety valve module (6) being connected to one component group. It is endeavoured to provide a valve arrangement with a high safety level. For this purpose, it is ensured that each control valve (2 to 5, 2' to 5') has an error detection device (19), that the safety valve module (6) has a safety switch device (21) and that the component group has a connection (20) between the safety switch device (21) and the error detection device (19).
