Two handle Enfield Thermostat shall feature a cast brass valve body. Thermostat shall be a wax element shuttle valve. Shall also feature ceramic disc valving, 1/2" NPT or 3/4" NPT inlets and outlets. Fitting shall be American Standard Model # R5_0.

PRODUCT FEATURES:

Brass Casting: Highest quality faucet material for durability &

long life.

Wax Thermostatic Unit: 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.
