Description

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 (1.52 to 2.44 m) downstream for the most accurate temperature measurement.)

  • A flow rate of 1 to 31 gpm (3.8 to 117.3 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 (65% of rated tepid flow rate)
  • Modular 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).
  • Tempered water: High temperature limit is factory set to 90® F (32® C).
  • Cold water by-pass valves are closed during normal operation, regardless of flow rate.

Technical Details

Model 9201E (patent pending) is a thermostatic mixing valve that mixes hot and cold water to supply tempered water to emergency shower and eyewash fixtures requiring flow up to 31 gpm (117.3 L). Unit employs a paraffin filled thermostatic mixing element. Lowest internal pressure drop where supply pressure is low, and a high Cold Water Bypass flow rate of 20 gpm (75.7 L). 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. Lime and calcium resistant components are used throughout. The outlet temperature factory setting is 85® F (26® C). Maximum operating pressure: 125 psi (8.62 Bar). Temperature adjustment range 60 – 90® F (16 – 35® C). Maximum inlet temperature: 180® F (82® C). Recommended inlet temperature: 140® F (60® C). Minimum inlet temperature: 120® F (49® C) Inlets 1-1/4″ NPT(F). Outlet 1-1/4″ NPT(F).
