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 deg F (26 deg C). Maximum operating pressure: 125 psi (8.62 Bar). Temperature adjustment range 60 - 95 deg F (16 - 35 deg C). Maximum inlet temperature: 180 deg F (82 deg C). Recommended inlet temperature: 140 deg F (60 deg C). Minimum inlet temperature: 120 deg F (49 deg C) Inlets 1-1/4 in FNPT. Outlet 1-1/4 in FNPT.
