Kohler HiFlow Thermostatic Valving offers separate water volume and precise temperature control adjustment with safety. This allows the user to set a comfortable water temperature and know it will remain at that setting for the next use. It automatically adjusts the mixture of hot and cold water in response to pressure and/or temperature changes to keep water temperature virtually the same. It features an automatic shut off if the cold water supply is interrupted as well as a safety stop at 104°F -- all to help prevent scalding. A manual safety stop override feature allows a maximum water temperature of 120°F.

FLOW RATE
KOHLER HiFlow Thermostatic valves deliver more than double the gpm of standard Rite-Temp valves.

FLOW RATE
The innovative design of MasterShower HiFlow Thermostatic Valving enables water to cascade at over 12 gpm* at 50 psi.

* Actual flow rates may vary according to plumbing system set-up.

SPECIFICATION TIPS:

• The flow rate capacity of the valve is determined by water pressure in pounds per square inch (PSI) at the point of hook-up. Using the flow rate chart, determine how many gallons per minute (GPM) can pass through the valve according to available PSI. Once you know the maximum flow rate, select the components you wish to use and make sure that their combined GPM does not exceed the flow rate of the valve.
• Make sure that the water heater and drain capacity can accommodate your custom shower arrangement. KOHLER Shower Drain K-9132 is recommended. If more than one valve is used in your arrangement, more than one drain may be required.
• For maximum results, use 3/4" supplies to the valve.
The K-400-K thermostatic valve is mixer valve only. A K-403-K volume control valve must be used in conjunction with K-400-K thermostatic valve.
• If using a diverter spout on a bath/shower installation, a twin ell (K-9663-NA) is required.
