Haws 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 improved low-lead 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" NPT(F). Outlet 1-1/4" NPT(F).
