Thermostatic mixer valve

Thermostatic valve (1), for mixer taps, comprising:

• a valve body (12, 13) having a longitudinal axis (X-X) and internally provided with a chamber (11) for mixing water,
• side openings (24, 25), provided at different heights of said valve body (12, 13) with respect to the longitudinal axis (X-X), for inflowing hot water (C) and cold water (F) separately in said mixing chamber (11);
• and
• automated means (17, 18, 19, 20) for regulating the flow rates of hot water (C) and cold water (F) incoming through said inflowing side openings (24, 25), wherein said regulating automated means (17, 18, 19, 20) comprise a thermostatic bulb (18) operating in said mixing chamber (11) and an element (17) for regulating the inflow rates of hot water (C) and cold water (F), movable along the longitudinal axis (X-X) in order to feedback close completely or partially, and selectively, said inflowing side openings (24, 25) in response to the expansions the thermostatic bulb (18) is subjected to, and
• wherein said valve body (12, 13) comprises a first quick—coupling portion (12a) shaped so as to mechanically and fluidically couple with a pressure regulator (27) adapted to regulate the flows of hot water (C) and cold water (F).
