Haws Thermostatic Mixing Valve - TWBS.SHE

Lead-free AXION Emergency Tempering Valve thermostatically mixes hot and cold water to provide a safe fluid supply for emergency shower and eyewash equipment, with a flow rate of 74 gpm (280 L).

Haws 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).

  • A flow rate of 1 to 74 gpm (280 L) for better temperature control across the operating range
  • AXION's superior design and technology provide a complete safety solution for increased victim comfort.
  • Lowest internal pressure drop for this class of valve (advantage where supply pressure is low)
  • Wax based thermostat technology for fast response time with proven highly reliable temperature control
  • Highest Cold Water Bypass flow rate in the industry (68% of rated tepid flow rate)
  • Modular lead-free brass design with internal check stops
  • Over-sized valve seats resist failures caused by foreign matter
  • A new and efficient shuttle design eliminates valve binding
  • A custom funnel design improves temperature control at low flow rates
  • Outlet temperature is factory set to 85° F (29° C)
