Model 9201E emergency mixing valve (patent pending) thermostatically mixes hot and cold water to provide a safe fluid supply for emergency showers and eyewash equipment. Additionally, to ensure a fail-safe water supply for emergency shower and 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 31 gpm (3.8 to 117.3 L) for better temperature control across the operating range. AXION'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 control. Highest Cold Water Bypass flow rate in the industry (65% of rated tepid flow rate). Modular brass design with internal check stops. Over-sized valve seats resist failures caused by foreign matter. A new and efficient shuttle design eliminates valve sticking. A custom funnel design improves temperature control at low flow rates. Outlet 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. CSA Certifies this product to perform according to the ASSE 1071 standard and applicable sections of CSA B125.3.
