Thermostatic mixing valve for use with multiple eye washes or single shower or safety station, accommodating water flows from 3 - 40 GPM. Internal cold water bypass allows for continued cold water delivery upon hot water failure. Dial thermometer indicates shower/eye wash temperature. Integral supply check stops prevent crossover of supplies. Valve is factory assembled and tested prior to shipment.
APPLICATION: Tempering valve to blend hot and cold water to deliver tepid water. Valve has flow capacity of 3.0 to 34 gallons per minute (GPM). Valve can be used with emergency shower, safety station or multiple installations of eyewash, eye/face wash, dual purpose eyewash/drench hose and drench hose units.

TEMPERATURE CONTROL: Valve has bimetallic thermostat that senses incoming water temperature and automatically blends water to 85å¡F (29å¡C). High temperature limit stop is set to 90å¡F (32å¡C). Valve has dial thermometer on outlet to monitor temperature of delivered water. Note: Valve may need to be adjusted when installed based on incoming water temperature. Refer to "Installation Instructions" for further information.

FAIL SAFE: In event of restriction or failure of hot water supply, internal bypass allows valve to deliver cold water to emergency unit. In bypass mode, valve will deliver 20 GPM of cold water at 30 PSI flow pressure. In event of loss of cold water supply, valve will close and not deliver water.

Refer to chart below for flow capacity of valve at specified pressure drops:
System Pressure Drop (PSI) 5 10 15 (more...)
