PRODUCT FEATURES:

Brass Casting:

Permits shuttle valve to move

between the hot and cold seats to maintain the pre-selected

constant water temperature.

Back to Back Capable:

Hot and cold can be reversed.

Spring-Loaded Check Valves:

When the hot and cold water

enters the fitting, both supplies pass through the spring-loaded

check valves to prevent cross flow of hot and cold water.

Integrated Stop Valves:

Ensure easy cleaning and servicing.

Adjustable Hot Limit Safety Stop:

Limits the amount of hot

water allowed to mix with cold. Reduces the risk of accidental

scalding. Maximum water temperature limit may be reduced to

104 or 109 degrees Fahrenheit.
