The device comprises a valve body with an input adapted to be connected to a water supply source, and with at least a first and second output. The body is provided with at least a first and a second electrovalve with direct actuation, whose hydraulic inputs are interconnected with one another and are connected to the input of the valve body and whose outputs are independent or separate and are connected to the first and the second output of the body respectively. The body is provided with a third solenoid electrovalve, for safety purposes, interposed between the input of the body and the inputs of the first and second electrovalves. Control devices are coupled to this third electrovalve such that the latter may be opened/closed each time that the first or second electrovalve is opened/closed. This third electrovalve closes in a delayed manner with respect to the closure of the first and the second electrovalve.
