This valve uses a rotatable balancing chamber to control the waterflow into the balancing chamber. A pair of exit ports on the rotatable balancing chamber are in communication with the balancing chambers on either side of a diaphragm equipped shuttle to control the outlet mixture of hot and cold water. The diaphragm equipped shuttle responds to changes in pressure in the respective balance chambers to throttle the water through the valve in response to changes in inlet pressures. The pressure balancing chambers are isolated from the water supplies feeding the valve when the valve is in the "off" position, and the pressure balancing chambers are pre-pressurized before any water is permitted to exit from the valve.
