A mixing valve which provides water of a constant temperature when connected to sources of hot and cold water. The valve comprises a cylindrical housing having first and second axially aligned spaced inlet connectors, a rotatable pressure selection element positioned within the housing, an axially translatable presure equalizing element positioned within the pressure selection element and a rotatable temperature selection element positioned within the pressure equalizing element. The pressure selection element has first and second ports substantially aligned with the inlet connectors to the housing, the pressure equalizing element has first and second ports axially aligned and angularly displaced from the first and second ports in the pressure selector and the temperature selection element has first and second ports angularly displaced with respect to each other and to the first and second ports in the pressure equalizing element. Rotation of the pressure selection element adjusts the volume of water discharged per unit time from the valve and rotation of the temperature selection element adjusts the ratio of hot to cold water discharged.
