Description
The Guardian G3850 Tempering Valve 44 Gallon (with Redundant Bypass) blends hot and cold water to deliver tepid water. The valve is supplied with an external bypass for “second stage” mixing of the water. The valve has a flow capacity of 3.0 to 44 gallons per minute (GPM). The valve can be used with single installation of drench showers and combination units, and with multiple installations of drench shower, eyewash, eye/face wash, combination drench hose & eyewash, and drench hose units.
- Temperature Control: Valve has bimetallic thermostat that senses incoming water temperature and automatically blends water to 85 degrees F. High temperature limit stop is set to 90 degrees F. 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.
- Internal 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.
- External Fail Safe: In addition to primary blending, unit is furnished with external thermostat to sense temperature of outlet tempered water. If temperature of tempered water rises above 90 degrees F, additional cold water is added to tempered water to lower water temperature to 90 degrees F.
- Supply Pressure: 30 PSI minimum supply pressure is required for proper operation of valve. Maximum supply pressure is 125 PSI.
- Mounting: Furnished with heavy duty mounting bracket for securing valve to panel or wall.
- Inlets: 1-1/4” NPT female hot and cold water top inlets. Each inlet has integral water strainer, check valve, and supply stop.
- Outlet: 1-1/4” NPT female outlet.
