Haws TWBS.SHE 1-1/4 x 1-1/4 in Emergency Tempering Thermostatic Mixing Valve

Model TWBS.SHE, low-lead 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 (3.8 to 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 deg F (29 deg C)
