Thermostatic Mixing Valve

Haws® Model TWBS.EWE Lead-free AXION® Emergency Tempering Valve thermostatically mixes hot and cold water to provide a safe fluid supply for emergency eyewash equipment, with a flow rate of 12 gpm (45.4 L).

• A flow rate of 1 to 12 gpm (3.8 to 45.4 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 (83% 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).

Specifications

Model TWBS.EWE (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 12 gpm (45.4 L). 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 lead-free 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 (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 1/2" NPT(F). Outlet 3/4" NPT(F).
