• A flow rate of 1 to 31 gpm for better temperature control across the operating range
• 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 (65 percent of rated tepid flow rate)
• Modular brass design with internal check stops

Haws emergency mixing valve thermostatically mixes hot and cold water to provide a safe fluid supply for emergency showers and eyewash equipment. Additionally, to ensure a fail-safe water supply for emergency shower and eyewash stations, a series of cold water by-pass valves open in the event of hot water pressure loss. Oversized valve seats resist failures caused by foreign matter. A new and efficient shuttle design eliminates valve sticking. A custom funnel design improves temperature control at low flow rates. Outlet temperature is factory set to 85 degree F. Tempered water: High temperature limit is factory set to 90 degree F. 0.4 gpm cold water failure rate when tested according to ASSE 1071. Cold water by-pass valves are closed during normal operation, regardless of flow rate. CSA Certifies this product to perform according to the ASSE 1071 standard and applicable sections of CSA B125.3. This model is a thermostatic mixing valve that mixes hot and cold water to supply tempered water to emergency shower and eyewash fixtures requiring flow up to 31 gpm. 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 20 gpm. A 0.4 gpm hot water flow if cold supply fails. The modular 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. Lime and calcium resistant components are used throughout. The outlet temperature factory setting is 85 degree F. Maximum operating pressure: 125 psi. Temperature adjustment range 60 - 95 degree F. Min/max inlet hot water temperature: 120 degree/180 degree F, with recommended inlet temperature: 140 degree F. Min/max inlet cold water temperature: 40 degree/70 degree F. Inlets 1-1/4-inches NPT(F). Outlet 1-1/4-inches NPT(F).
