Bradley Company, the globally specified leader in drench shower and eyewash fixtures, is the only manufacturer that manufactures both thermostatic mixing valves and emergency safety fixtures. Navigator® Emergency Valves provide reliable tepid water to the safety fixture to achieve 15 minutes of washdown per ANSI 358.1 requirements. These valves are designed with technology to provide precisely tempered water to eye/face washes, drench showers and combination drench shower and eye/face wash units.
Navigator thermostatic mixing valves are engineered to mix incoming hot and cold water to a tepid temperature of 65°F to 95°F (18°C to 35°C), which is conducive to completing the full 15-minute flush. With accurate temperature control to within +/-3 °F, this assures that a user won’t be subjected to very cold water and possibly hypothermia or very hot or scalding water and possibly skin burns.
Specifically, a built-in cold water bypass assures cold water flow if hot water fails or the thermostat loses charge so the user can still get relief in an emergency. A positive shutoff of hot supply when cold supply is lost is also important so the user isn’t exposed to hot water. Each of these features are key in an emergency situation, so the injured person can still get immediate washdown relief without further distress or injury.
The Navigator Valve also offers easy installation and serviceability, with an adjustable set point range with a hex key set screw. Integral checkstops with strainers on the hot and cold inlets are standard.
Other key features include universal mounting capability, maximum operating pressure of 125 psi (860 kPA), and maximum inlet temperature of 180°F (82°C) with recommended inlet temperature of 120°F to 140°F (49°C to 60°C). There is also a 10-year warranty on the liquid-filled thermostat.
With Bradley being the only manufacturer that makes both the Emergency fixture and the Emergency Valve, it is easy to find the cross reference for each fixture and valve.
Navigator® TMV Offers Two Valves in One
Bradley also offers space-saving access to both tempered water and tepid water with its 2-in-1 Navigator® Thermostatic Mixing Valve. Engineered to deliver safe water temperatures to both commercial faucet applications as well as emergency safety eyewash fixtures, this model provides a complete and efficient single mixing valve solution.
With its innovative combination of two valves in one, the Navigator TMV saves on installation time and conserves space under sinks. During regular faucet use, the TMV has a hot and cold water outlet to deliver tempered water for uses such as handwashing; in an emergency, the valve delivers tepid water to the emergency safety eyewash to meet the ANSI/ISEA Z358.1 standard for the required 15-minute flush.
The Navigator TMV is ASSE 1070 and 1071 Certified, and includes a 3/8″ compression fitting to install to the faucet. A reliable liquid-filled thermostat ensures safe water temperature to the eyewash, and a separate wax filled thermostat delivers safe water temperature to the faucet.
With its built-in safety features, the cold water bypass on the eyewash assures cold flow if hot water fails. Navigator TMV also offers anti-scald protection with positive shutoff of hot supply when cold supply is lost.
Designed for reliable precision, Navigator TMVs deliver accurate temperature control to within ± 3° and features an adjustable set point within temperature range.
Ready for easy direct mounting to walls, all materials are 100% factory assembled and tested.
