Abstract
The invention concerns a valve arrangement () with a high-pressure connection (P), a low-pressure connection (T), at least one control valve (to), which is accommodated in a control valve module and has at least one working connection (A, B) for a hydraulic consumer (to), and a safety valve (), 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 (to), the control valve module (to) and the safety valve module () 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 (to' to′) has an error detection device (), that the safety valve module () has a safety switch device () and that the component group has a connection () between the safety switch device () and the error detection device ().
