Abstract
A mixing valve for two fluids under pressure at different temperatures. The mixing valve has a body with means defining a valve chamber, separate inlet ports for each of the fluids to be mixed, and an outlet port. A main mixing valve unit projects into the valve chamber. The mixing valve also has a means for causing axial movement of the main mixing valve unit within the main valve chamber while preventing rotation of the main valve unit relative to the valve chamber.
