Thermostatic Mixing Valve Haws 9201E
Guaranteed Lowest Price- Call Us!
Haws Model 9201 is a thermostatic mixing valve that mixes hot and cold water to supply tempered water to one or more emergency eyewash fixtures requiring flow up to 31 gpm. The unit employs a paraffin filled thermostatic mixing element. The modular brass design with a one piece casting uses internal check stops, oversized valve seats, a shuttle design that eliminates valve sticking, and a funnel design to improve temperature control with better mixing at low flow rates.
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 downstream for the most accurate temperature measurement.)
•A flow rate of 1 to 31 GPM for better temperature control across the operating range
•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
•Oversized 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).
•0.4 GPM cold water failure rate when tested according to ASSE 1071.
•Cold water by-pass valves are closed during normal operation, regardless of flow rate.
CSA Certified to ASSE 1071, and applicable sections of CSA B125.3.

Industry Standards Compliant
Where the eyes of any person may be exposed to injurious or corrosive materials, emergency facilities for quick drenching or flushing of the eyes and body with tempered water is needed to compensate for less than suitable ambient temperatures, or when the supply water reaches freezing cold or scalding hot temperatures.
