Mixing valve, thermostatic, for eyewash assembly, blends hot and cold water to deliver warm (tepid) water, use with G1814BC eyewash unit, sold by the each

Application: EyeSafe™ faucet-mounted eyewashes convert any faucet into an emergency eyewash station without interfering with normal faucet operation. An EyeSafe™ unit can be installed at any sink, close to where accidents might occur. In an emergency, the unit is quickly located and activated, and provides an unlimited supply of potable water for rinsing the user’s eyes. Faucet control valve offers single motion eyewash activation by allowing the pull knob to control water flow while the faucet remains ‘on’ at a preset temperature.
Operation: Unlike conventional faucet-mounted eyewashes, the G1200 offers the ability to activate the eyewash in a single motion. The unit is equipped with a diverter valve for the eyewash and a separate control valve for the faucet. Once the unit is installed on a faucet, the faucet may be opened and left “on” to a preset temperature. To use the faucet, the flow of water is controlled by a quarter-turn ball valve and knob at the bottom of the eyewash. To use the eyewash, simply pull the knob on the front of the eyewash. Since the faucet is open, this is the only step required to activate the eyewash. Water pressure holds the eyewash in operation, leaving the user’s hands free. To return to normal faucet operation, push the knob in or turn off the faucet.
Outlet Heads: Outlet heads are mounted 3″ apart and deliver a soft, aerated flow of water. Heads angle forward toward user. Angle of heads is adjustable to permit full coverage and avoid splashing. Furnished with float-off dust covers to protect outlet heads.
Eyewash Valve: Forged brass diverter valve.
Faucet Control Valve: Quarter turn ball valve with chrome plated brass ball, molded PTFE seals and plastic handle.
Inlet: Body has 55/64″-27 female thread. Furnished with three adaptors (15/16″-27, 13/16″-27 and 3/8″ NPS) for installing on most commonly used faucets, including laboratory-type faucets.
Outlet: Furnished with removable aerator on bottom.
Quality Assurance: Each unit is completely assembled and water tested prior to shipment.
Important: Faucet-mounted eyewashes are intended solely as supplemental units in addition to dedicated, plumbed eyewash equipment installed in the workplace.
Faucet-mounted eyewashes should be used with cold or warm water only. Use of hot water might cause scalding.
Leaving a faucet “on” with a valve at the outlet closed can cause cross-mixing of the hot and cold water. The water supply lines or the faucet should be furnished with check valves to prevent such mixing from occurring. This unit should not be installed on a faucet with an atmospheric vacuum breaker, as the faucet control valve downstream of the vacuum breaker will interfere with its function. Guardian Equipment recommends consulting with local plumbing code authorities prior to installing this unit.

Quality Assurance: Unit is completely assembled and water tested prior to shipment.

Application: Tempering valve to blend hot and cold water to deliver tepid water. Valve is installed in stainless steel cabinet designed for recess mounting in finished wall. Valve has flow capacity of 2 to 6 gallons per minute (GPM). Valve can be used with an eyewash, eye/face wash, dual purpose eyewash/drench hose or drench hose unit.
Temperature Control: Valve has bimetallic thermostat that senses incoming water temperature and automatically blends water to 85°F (29°C). High temperature limit stop is set to 90°F (32°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” on the following page 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 4 GPM of cold water at 30 PSI flow pressure. In event of loss of cold water supply, valve will close to prevent scalding and not deliver water.
Flow Capacity: Refer to chart below for flow capacity of valve at specified pressure drops:

Supply Temperature: Minimum recommended hot water supply temperature is 120°F (49°C). Note: Extremely cold climates may require a hot water supply temperature greater than 120°F (49°C).
Supply Pressure: 30 PSI minimum supply pressure is required for proper valve operation. Maximum supply pressure is 125 PSI. Maximum hot to cold water pressure differential is 5%.
Mounting: Tempering valve is mounted in 16 gauge Type 304 stainless steel cabinet with flange featuring 3/8” return for recessed mounting in wall. Cabinet has hinged door with lock.
Inlets: 1/2″ nominal sweat female hot and cold water inlets. Each inlet has check valve and supply stop.
Outlet: 1/2″ NPT female outlet.
Quality Assurance: Valve is completely assembled and water tested prior to shipment. Valve is certified to ASSE 1071. Valve is certified to meet low lead requirements of wetted surface area less than 0.25% lead by weight.
Important: Pursuant to ANSI Z358.1-2014, the water delivered by emergency equipment should be “tepid”. Tepid is defined as moderately warm or lukewarm, and is generally considered to be between 60°F (15°C) and 90°F (32°C). However, in certain circumstances, a chemical reaction may be accelerated or otherwise affected by the water temperature. Please consult with a medical advisor to determine the optimum delivered water temperature prior to specifying, installing or using a tempering valve.
Tempering valves will not deliver the appropriate water temperature if the system has not been sized correctly. Please refer to the flow capacities and supply pressure requirements listed above when designing the tempered water system and selecting tempering valves.
Tempering valves, like all emergency eyewash and shower equipment, must be installed in accordance with the manufacturer’s instructions and maintained on a regular basis. Under ANSI Z358.1-2014, all emergency equipment should be activated weekly and inspected at least annually. Tempering valves should be treated the same and, in addition, must be regularly cleaned and cycled.

APPLICATION NOTE: These products were discontinued in September, 2021. Repair parts are no longer available. The Guardian G604X series of valve cabinets is a higher capacity, lower maintenance, and more affordable tempering valve that is designed as the successor to the G3800LF.
The G3802LF is a G3800LF tempering valve contained within a surface-mounted steel cabinet. The G3807LF is a recess-mounted cabinet (select the “recess mount” checkbox above to select). This series of valves is suitable for use with a single installation of emergency showers and safety stations, and with multiple installations of emergency shower, eyewash, eye/face wash, dual purpose eyewash/drench hose, drench hose and safety station units. The G3800LF valve is available in two additional configurations.
We carry a full line of tempering valves ranging in capacities from 6 to 81 gallons per minute (GPM). The valve must be properly matched to the flow capacity of the safety station in order to deliver water within the tepid range.
