A motorised valve carries components of an electronic control circuit for the corresponding motor on a plate (10) secured on a frame (9) by fastening means, for example a pair of screws (12), the plate being such that it may be laterally removed without the need to remove any of the remaining valve mechanisms. Furthermore, electronic components (14) of the circuit are laterally protected from possible contact with a metallic element, e.g. a screw-driver, by means of an electrical insulating element (15), there being provided further protecting elements (20) for the microswitches (18) which also constitute components of the said circuit. <IMAGE>
