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. 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. A 0.0 GPM hot water flow if cold supply fails. The modular lead free brass design with a one piece casting uses internal check stops, oversized valve seats, a shuttle design that eliminates valve sticking, and a funnel design to improve temperature control with better mixing at low flow rates. Calcium and lime resistant components are used throughout. The outlet temperature factory setting is 85°F (26°C). Maximum operating pressure: 125 PSI. 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).
