ABSTRACT:
A control device for controlling and monitoring two fluid valves, wherein each fluid valve comprises a drive means which is adapted for activation by an associated control signal, and a movable valve element which is biassed toward a first position in which fluid flow through the valve is prevented and which can be driven by said drive means to a second position in which fluid is able to flow through the valve, a first switch which is actuable by the displaceable element of the first valve, a second switch which is actuable by the displaceable element of the second valve, wherein each switch is biassed towards a first position and each switch can be driven to a second position when the displaceable element of the associated valve takes its second position.
