Guardian Equipment, G6040, Thermostatic Mixing Valve, Gallon/189 Liter CapacityFeatures:Temperature Control. Valve shall have a precision thermal actuator to accurately blend hot and cold water. Valve is factory preset to deliver 85° F (29° C) tepid water with high temperature limit stop at 90° F (32° C). Temperature can be adjusted in field up to limit and locked.Capacity. Valve shall have a flow capacity of GPM (189 L/min) at 30 PSI (2.1 bar) pressure drop. Failsafe Protection. In event the hot water supply fails, the valve shall deliver cold water only (i.e. bypass mode) at a flow rate of 38 GPM (144 L/min) at 30 PSI pressure drop. In the event the cold water supply fails, the valve shall close and not deliver any water at all.Supply Pressure. Maximum supply pressure is 125 PSI. Pressure of hot and cold water supplies can vary up to 25% and still deliver the flow and temperature required by ANSI/ASSE 1071.Construction. Valve shall be furnished with lockable shutoff valves on the hot and cold water supplies, internal check valves to prevent cross-mixing of hot and cold water and stainless steel basket filters to remove debris from the water flow. Valve shall be furnished with outlet temperature gauge and stainless steel mounting bracket. Valve shall meet the requirements of the U.S. Safe Drinking Water Act as lead-free.Inlets/Outlet. Valve shall have 1" NPT female inlets and 1-1/4" NPT outlet. Inlets can be positioned in the field for top, back or bottom supply. Outlet can be positioned on top or bottom.Quality Control. Valve shall be third-party certified to comply with ANSI/ASSE 1071 and shall be fully assembled and factory tested prior to shipment.For more information, please see Data Sheet.
