Grainger Haws Thermostatic Mixing Valve, Brass, 31 gpm, Lead Free

Catalog No. 502792319
Encompass_Preferred

The thermostatic mixing valve is designed to mix hot and cold water for emergency showers and eyewash equipment. Utilizing paraffin-based thermal actuation, the unit maintains consistent outlet temperatures to prevent scalding and hypothermia, while a secondary high-temperature limit valve provides redundant anti-scald protection. Its funnel design promotes turbulent flow for precise temperature blending, and the low-lead brass construction resists lime and calcium deposits for enhanced durability.

  • Flow range of 1 to 31 GPM (117.3 L)
  • Best-in-class cold water bypass flow at 65% of rated tempered flow
  • Redundant anti-scald protection with internal cold water bypass
  • Superior shuttle design to eliminate valve binding
  • Lead-free construction compliant with NSF 61 and AB 1953-2006
  • Lowest internal pressure drop in valve class
  • 3-year extended warranty
