The invention concerns a valve arrangement (1) with at least two valve modules (2, 4, 5), each having a valve element, whose position can be changed by means of an actuator (13, 13a, 13b), and to which a position sensor (19, 19a, 19b) is allocated, a line arrangement (24) being connected with the valve modules (2, 4, 5), through which control signals can be transmitted to the valve modules (2, 4, 5). It is endeavoured to increase the safety of such valve modules. For this purpose, at each valve module (2 to 5) the actuator (13) is provided with a control device (22, 22a, 22b), which is connected with the position sensor (19, 19a, 19b) and evaluates control signals for the valve module (2 to 5) concerned, that at least the control device (22b) of a first valve module (5) additionally evaluates the control signals for another, second valve module (4), and that this control device (22b) receives signals from the position sensor (19a) of the second valve module (4).
A valve arrangement with at least two valve modules, each having a valve element, whose position can be changed by means of an actuator, and to which a position sensor is allocated, a line arrangement being connected with the valve modules, through which control signals can be transmitted to the valve modules, wherein at each valve module the actuator is provided with a control device, which is connected with the position sensor and evaluates control signals for the valve module concerned, that at least the control device of a first valve module additionally evaluates the control signals for another, second valve module, and that this control device receives signals from the position sensor of the second valve module.
