Model 9201EFE Emergency Thermostatic Mixing Valve (patent pending) thermostatically mixes hot and cold water to provide a safe fluid supply for emergency eyewash equipment. Additionally, to ensure a fail-safe water supply for emergency eyewash stations, a series of cold water by-pass valves open in the event of hot water pressure loss. (No gauges supplied - ASSE 1071 standard recommends gauges be placed 5 to 8 feet (1.52 to 2.44 m) downstream for the most accurate temperature measurement.)A flow rate of 1 to 12 gpm (3.8 to 45.4 L) for better temperature control across the operating rangeAXION's superior design and technology provide a complete safety solution for increased victim comfort.Lowest internal pressure drop for this class of valve (advantage where supply pressure is low)Wax based thermostat technology for fast response time with proven highly reliable temperature controlHighest Cold Water Bypass flow rate in the industry (83% of rated tepid flow rate)Brass valve design with internal check stopsOver-sized valve seats resist failures caused by foreign matterA new and efficient shuttle design eliminates Thermostatic Mixing Valve stickingA custom funnel design improves temperature control at low flow ratesOutlet temperature is factory set to 85° F (29° C).Tempered water: High temperature limit is factory set to 90° F (32° C).Cold water by-pass valves are closed during normal operation, regardless of flow rate.For important installation information, please read Scald Warning.CSA Listings: CSA certified per ASSE 1071, ANSI/ISEA Z358.1 and applicable sections of CSA B125.3.Prop 65 Warning.
