Bradley Thermostatic Mixing Valves blend hot and cold water to a tepid flushing temperature (65º-95ºF). ANSI Standards require tepid water to assure the eyewash and drench shower do not subject the user to scalding or freezing water temperatures. Bradley valves feature an exclusive fixed cold-water bypass, which allows only cold water to flow through the valve in the event of loss or interruption of hot water supply or thermostat malfunction. These valves are pre-set at 85ºF, but can be adjusted to other temperature set points. Valves are available in a variety of options to accommodate various equipment applications.
