Mixing thermostatic valve TWBS.SHE

temperature controlbrassfor water

Model TWBS.SHE, lead-free Emergency Valve (patent pending), thermostatically mixes hot and cold water to provide a safe fluid supply for emergency shower and 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.) A flow rate of 1 to 74 gpm (280 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 (68% of rated tepid flow rate) Modular lead-free brass design with internal check stops Over-sized valve seats resist failures caused by foreign matter A new and efficient shuttle design eliminates valve binding 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 87° F (30° C) Cold water by-pass valves are closed during normal operation, regardless of flow rate
