Abstract: The present invention pertains to a mixer valve with electronic control, which incorporates a group of valves (27) arranged in a housing (26) provided in the valve body axially to the coupling (22) which defines the water outlet duct towards the supply mouth. The group of valves consists of a diaphragm valve (30), which is made of an elastic material and essentially has the shape of a small bowl, arranged at the level of a valve seat (32) on the inside of the outlet duct (21), and the group consists of a stop valve (31) which is controlled by an electromagnet (29). The diaphragm valve (30) delimits an internal chamber (35), which communicates, from one component (A), with a mixed water supply duct (24), and from another component (B), with an outlet port (C) which is connected to the drain duct (21) and which is opened and closed by the stop valve.
