A thermostatic mixing valve (TMV) including a low-flow passageway and a high-flow passageway connecting a mixing chamber and a sensing chamber, and a check valve received in the high-flow passageway adapted to open and allow additional flow from the mixing chamber to the sensing chamber upon fluid flow through the valve rising to at least a predetermined high flow rate. The TMV accommodates a wide range of flows yet does not allow excess flow to bypass the sensing chamber which contains a thermal motor of the valve. Even at high flow rates, therefore, the TMV accurately mixes fluid.
