Tempering valve for point-of-use mixing

The Chicago Faucet Company 131-ABNF is a thermostatic mixing valve built for point-of-use temperature control. It connects via 3/8 inch compression fittings and is constructed from brass. The valve meets ASSE 1070, AB1953 and VT S. 152 compliance standards.

Flow range and temperature limits

The unit delivers a flow rate between .5 and 6.6 gallons per minute and operates within a temperature range of 80 to 120 degrees Fahrenheit. It is rated for a maximum pressure of 125 PSI. Installations requiring higher flow volumes or pressure ratings will exceed the valve's design limits.

Compression connection and standard constraints

The 3/8 inch compression connection suits standard supply stops but does not adapt to threaded or sweat fittings without additional parts. ASSE 1070 certification covers point-of-use tempering only; the valve is not rated for high-temperature source distribution or whole-building mixing applications.

Questions about this item

Will the 3/8 inch compression connections on this 131-ABNF valve fit the copper supply lines I already have?

The valve uses 3/8 inch compression fittings, a common size for residential copper supply stops, so it should thread onto existing 3/8 inch OD tubing without adapters.

How can I verify the tempering valve is mixing water to a safe temperature after installation?

Run the mixed outlet and measure the temperature with a thermometer; the valve is factory-set to deliver between 80 and 120 degrees Fahrenheit per ASSE 1070.

Does the 131-ABNF package include supply nuts, ferrules or any tailpieces, or must I buy them separately?

The box contains the brass tempering valve body only; 3/8 inch compression nuts, ferrules and any supply tubes are sold separately.
