Guardian G3602LF and G3607LF Tempering Valves, 6 Gallon Capacity w/ Mounted Stainless Steel Cabinet

Item #: G3602LF
Discontinued; see below.

Normal Availability: Discontinued; see below.

Product Description

APPLICATION NOTEThese products were discontinued in September, 2021.  Repair parts are no longer available. The Guardian G602X 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 G3602LF is a G3600LF tempering valve contained within a surface-mounted steel cabinet.  The G3607LF is a recess-mounted cabinet (select the "recess mount" checkbox above to select).  This series of valves is ideal for eyewash and drench hose stations (showers and combination safety stations require higher capacities).

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.  

Application: Tempering valve to blend hot and cold water to deliver tepid water. Valve has flow capacity of 2 to 6 gallons per minute (GPM). Valve can be used with 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 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” 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 and not deliver water.

Flow Capacity: Refer to chart below for flow capacity of valve at specified pressure drops:

System Pressure Drop (psi) 5 10 15 20 25 30 35 40
Flow rate (gallons per minute) 2.0 2.7 3.5 4.5 5.5 6.5 7.5 8.5
System Pressure Drop (bar) 0.3 0.7 1.0 1.4 1.7 2.1 2.4 2.8
Flow rate (liters per minute) 7.6 10 13 17 21 25 28 32

Supply Temperature: Minimum hot water supply temperature is 140 °F (60 °C).

Supply Pressure: 30 PSI minimum supply pressure is required for proper operation of valve. Maximum supply pressure is 125 PSI. Maximum hot to cold water pressure differential is 5%.

Mounting: Tempering valve is mounted in either a surface mounted cabinet (G3602LF) or recess-mounted model with a 3/8” return (G3607LF). Both cabinets have a hinged door with lock and are constructed from 16 gauge Type 304 stainless steel.

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.

Option Available: PRT - Adds a view port in cabinet door.

Application Note: 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.


Documentation available:  G3602LF and G3607LF specification sheets w/ measured drawings, installation, operation and maintenance guideG3602LF written specifications and G3607LF written specifications (Word format).

Weight/dims - The stainless steel enclosure measures 10" h x 10" w x 5" d (26 x 26 x 13 cm) and the shipping weight is 21 lb (9.5 kg).
