The G9802LF is a G3900LF tempering valve contained within a surface-mounted steel cabinet. The G3907LF is a recess-mounted cabinet (select the "recess mount" checkbox above to select). This unit 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.
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 3.0 to 81 gallons per minute (GPM). Valve can be used 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.
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 40 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)||53||64||72||81||90||99||108||117|
|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)||201||242||273||307||341||374||409||443|
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 (G3902LF) or recess-mounted model with a 3/8” return (G3907LF). Both cabinets have a hinged door with lock and are constructed from 16 gauge Type 304 stainless steel.
Inlets: 1-1/4" NPT female hot and cold water inlets. Inlets can be rotated 360 degrees for top or bottom supply. Each inlet has integral water strainer, check valve and supply stop.
Outlet: 1-1/2" 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.
Dimensions - The stainess steel enclosure measures 16" h x 16" w x 8" d (41 x 41 x 20 cm).
2-year manufacturer limited warranty.
