Feature: 1.Work pressure: 0.05Mpaâ??1Mpa ***** pressure: 0.1Mpaâ??***** pressure rudicing valve when exceed ideal pressure. 3.Standard pressure: Dynamic pressure0.3±0.02Mpa. ***** water supply temperature: 4-29â?? hot water supply temperature: 55-85â??. Advice water supply temperature55-70â??. ***** water tempertature range: 20-50â??. 6.Set the safety temperature at 38â??. 7.Satety characteristic: If cold water supply fails, flow rate will be reduced to virtually shut off which avoid the risk of scalding. ***** accuracy:Kept constant ±1â?? for the setting. ***** water temperature stability:when the temperature of water intake kept constant, Cold water or hot water pressure change 50% , the outlet water temperature changes in ±2â?? of setting temperature. The supply water pressure kept constant;the temperature for hot water supply can be increases from 60â?? to 75â??ï¼?5â??/minï¼?, the outlet water temperature changes in ±2â?? of setting temperature. ***** with the following standard: ASMEA112.1812005/CSAB125.1-05, ASSE1016, EN1111, AS-4032.1 and QB2806-2006
