HawsÂ, , Lead Free Thermostatic Emergency Mixing Valve, 74 GPM (Discontinued)

Haws lead free thermostatic emergency mixing valve, 74 gpm model twbs.she (patent pending) is a thermostatic mixing valve that mixes hot and cold water to supply tempered water to emergency eyewash fixtures requiring flow up to 74 gpm (280 l). Unit employs a paraffin filled thermostatic mixing element and a secondary high temperature limit valve to provide additional protection. Lowest internal pressure drop where supply pressure is low, and a high cold water bypass flow rate of 50 gpm (189 l). The improved lead-free brass design with a one piece casting uses internal check stops, over-sized 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) inlet 1-1/4" npt(f). Outlet 1-1/4" npt(f).
