Product Features

1/2″ thermostatic pre-mixing valve with DN15 check valves; the compact size makes it ideal for under sink applications.

It allows the supply of mixed water to single water inlet taps ensuring comfort and safety during use. The mixer avoids the danger of accidental burns; in case of lack of cold water it cuts off the hot water supply (FEATURE ANTI-SCALD).

The mixer is equipped with DN15 check valves. The mixer water temperature can be locked by means of a fixing screw. The temperature can be set to different values from the preset one, within the range (25-60 °C), and the control knob can be locked in the new position.


Setting: 37 ° C, tolerance +/-2° C.

Security Lock by knob screw.


To change the preset temperature make sure to loosen well the locking screw at the side of the hexagon, otherwise the rotation of the screw is hard and there is the risk of ruining the hexagon for the allen screw placed in the upper part of the valve.
