Model TWBS.HF, 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 pressure sensing diverter valve is provided that sends a pressure signal to open the cold water by-pass valve in the event of hot water pressure loss, main valve thermostat malfunction, or clogged cold water check-stop. (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 78 gpm (295 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 (100% 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 sticking
A custom funnel design improves temperature control at low flow rates
Outlet temperature is factory set to 85° F (29° C)
