TWBS.EWE – Thermostatic Mixing Valve

Model TWBS.EWE, lead-free Emergency Valve (patent pending) thermostatically mixes hot and cold water to provide a safe fluid supply for emergency eyewash equipment. The valve contains a secondary high temperature limit valve to provide additional protection to the user in the event of main tempering valve malfunction. 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.)
