The W39-N1750 compression thermostatic mixing valve is typically applied for wash basin in the public place like hotels, shopping malls to save energy and be with anti-scalding, which can supply the mixing water at a constant temperature as well as minimizing bacteria to keep health for users. Comparing with normal TMVs, the W39-N1251 is different, with lead free brass certified with cUPC and ASSE1070 approved.
