Abstract
Embodiments include eyewash valves in which the temperature of the water emerging from the valve is thermostatically controlled by a wax motor which regulates the flow of hot and cold water through the valve. Embodiments include provisions for continuing water flow through the valve despite failure of the hot water supply. Embodiments also include provisions for water flow through the valve despite failure of the wax motor in the upper position or in the lower position.
