ABSTRACT:
A mixing valve includes a sleeve with axially spaced inlet and outlet ports and a valve member movable within the sleeve to control flow from the inlet to the outlet. There is a seal at the inlet port, which seal extends through the sleeve and into contact with the valve member. The valve member has a first portion adjacent the inlet port to control flow of the fluid therethrough and a second portion adjacent the outlet port to similarly control flow of fluid therethrough. The first and second valve member portions are spaced apart a distance such that movement of the valve member toward a closing position causes the second portion to close the oulet port before the first portion closes the inlet port thereby reducing pressure on said seal means at closure of said inlet port.
