摘要： A solenoid valve with protective cap (10) having electrical connection elements (11, 13) attached to the cap fits only the electromagnet (2) of a solenoid valve (1). A cavity (12) situated in the cap makes it possible to add on circuit band unit (20) providing circuits which complement the solenoid valve but vary from user to user. Cable connection elements, elements for visual indication of the functional state, delay circuits, interference-suppressing circuits, intrinsic safety circuits, circuits for detecting the position of the moving core, circuits for detecting the presence of fluid, logical indexing circuits etc. may be mentioned as examples of circuit elements which complement the solenoid valve. The solenoid valve also comprises connection elements (18) which permit a rational and cableless electrical link between at least two solenoid valves. The present invention simplifies standardization of the solenoid valve and hence its manufacture, and simplifies its installation and its connection in situ by virtue of the fact that the various circuit devices required by the user are concentrated on the solenoid valve itself.
