ABSTRACT:
A water valve assembly includes a valve body having defined therein (1) a first fluid inlet, (2) a temperature sensing port, (3) a fluid outlet, and (4) a fluid channel in fluid communication with the first fluid inlet, the temperature sensing port, and the fluid outlet. The assembly also includes a first water valve being in fluid communication with the first fluid inlet. The assembly also includes a sensing device having a temperature sensing surface being positioned in thermal communication with the temperature sensing port. In addition, the assembly further includes a pressure inlet member having a pressure channel defined therein. The sensing device further has a pressure sensing surface, and the pressure channel is positioned in fluid communication with the pressure sensing surface. A method of operating a water valve assembly is also disclosed.
