Model 9201H (patent pending) is a lead-free 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 two paraffin filled thermostatic mixing elements. 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 in FNPT. Outlet 1-1/4 in FNPT.
