A mixing valve (10) includes a manifold (12) defining a hot fluid inlet (18), a cold fluid inlet (14), a temperature-controlled fluid outlet, and a cold fluid outlet. The cold fluid inlet is in fluid communication with the cold fluid outlet, and the cold fluid inlet and the hot fluid inlet are in fluid communication with the temperature-controlled fluid outlet. The manifold further defines a mixing chamber (22) for mixing of cold fluid from the cold fluid inlet and hot fluid from the hot fluid inlet. Mixed fluid from the mixing chamber (22) is delivered to the temperature-controlled fluid outlet. A temperature-controlled device (26) associated with the hot fluid inlet (18) controls the volume of flow from the hot fluid inlet to the mixing chamber. The mixing valve further includes a one-way check valve (28) located between the hot fluid inlet and the cold fluid outlet for limiting flow of hot fluid to the cold fluid outlet.
