We never want to have to use our emergency eyewash stations, but if we do need to use one we don’t want ice cold water hitting our eyeballs. In the ANSI Z358.1-2009
requirements the water supplied to emergency stations must be tepid (between 60 and 90°F ). Plumbed eyewash stations will need a tempering or mixing valve for mixing hot and cold water to comply with the ANSI requirement. Watersaver Faucet supplies a tempering valve to blend hot and cold water for delivering tepid water. The Water Saver tempering valve is specifically designed for plumbed eyewash and eye and face wash stations.
The tempering valve has a thermostat which detects the temperature of the hot water and blends the hot and cold water to 85°F. The high cut off for the tempering valve is 90°F, based on an incoming water temperature of <140°F. Flow capacity is 0.5 to 6 gpm (gallons per minute) and the inlet and outlet is 1/2 in NPT. The tempering valve is available as is, in a surface mounted stainless steel cabinet, or in a recess mounted stainless steel cabinet.
