Abstract: A thermostatic mixing valve and method of use thereof. The thermostatic mixing valve is controlled by the incoming hot and cold fluids, which are mixed in a mixing chamber, by a thermally responsive element disposed in the flow of the fluid mixture in a fluid outlet from the mixing chamber. A distributor for distributing the flow is controlled by the thermally responsive element. A drive is activated by pressure of the fluid and is connected to the distributor for controlling the position of the drive. The distributor is used to control the hot and cold fluid flows. Channels are provided to connect the distributor with one of the fluid inlets, to connect the distributor with the outside of the valve body to conduct away used operating fluid and to connect the distributor with the drive.
