Description
Haws Emergency Valve For Eyewash Station, 12 GPM Model 9201EFE (patent pending) is a thermostatic mixing valve that mixes hot and cold water to supply tempered water of up to 12 gpm (45.4 L) for emergency eyewash fixtures. 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 10 gpm (37.8 L). The improved brass design with a one piece casting uses internal check stops, over-sized valve seats, a shuttle design that eliminates valve binding, 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 (29 C). Maximum operating pressure: 125 psi (8.62 Bar). Temperature adjustment range 60 - 90 F (16 - 35 C). Min/max inlet hot water temperature: 120/180 F (49/82 C), with recommended inlet temperature: 140 F (60 C). Min/max inlet cold water temperature: 40/70 (4.4/21.1 C). Inlet 1/2" NPT(F). Outlet 3/4" NPT(F).
