Model 9201EF is a thermostatic mixing valve that mixes hot and cold water to supply tempered water to fixtures requiring flow up to 7 gpm @ 30 psi, sufficient for a single eye-eye/face wash. The unit employs a thermostatic mixing element and includes an outlet temperature gauge.
Tempered Water: The thermostatic mixing element responds to changes in incoming hot and cold water temperatures to maintain outlet temperatures to +/- 5°F (2.5°C). Varying conditions can be up to a 30°F (16°C) change in hot water temperature, 30°F (16°C) change in cold-water temperature, and a 50% drop in inlet supply pressure. Inlet hot and cold pressures must be equal. The outlet temperature factory setting is 80°F (26°C).
Fail-Safe Back Up: The 9201 EF employs patented thermostatic elements and will safely temper water to flows as little as 2 gpm. System shuts off all incoming hot water should cold water supply fail. Should the hot water supply become interrupted or the thermostatic element fails, the valve will go into cold-water bypass mode.
Maximum inlet pressure: 125 psi. Maximum inlet temperature: 180°F (82°C). Recommended inlet temperature: 140°F (60°C). Minimum inlet temperature:120°F (49°C).
Inlet and Outlet: 1/2" NPT inlet and 3/4" NPT outlet; Supplied with check valves.
