The main body of copper cartridge thermostatic concealed shower valve uses HPb59-1(grade A brass).
Zinc alloy made faucet handwhell is anti-oxidation and corrosion-resistant.
The HPb59-1 panel is anti-oxidation and corrosion-resistant.
The cartridge is copper thermostatic cartridge that can effectively prohibit the growth of the bacteria.
1. The optimum working pressure is 0.5-5Bar, you need a pressure-increasing valve when the pressure is lower than 0.5Bar.
2.The outlet temperature of the cold water is 4℃-25℃and the hot water is 55℃-85℃.
3.The safety temperature is set at 38℃(±2℃).
4.Anti-scald: When the cold water fails to supply: during the first 5 seconds (±0.5 seconds) the outlet temperature is within 49℃ in the condition of the outlet water volume less than 200ml, otherwise the temperature is less than 42℃ and the volume is less than 300ml; the temperature is below 49℃ in the following 30seconds. Besides, the temperature difference between the outlet water and the set temperature should be within 2℃.
5. Stable outlet water temperature: when the inlet water temperature is stable and the inlet pressure is 0.3 MPa then either pressure of the cold or hot water reduces to 20%; or when the inlet pressure is 0.3 Mpa, the inlet temperature of hot water varies by 10%, eventually the outlet water temperature difference is within 2 ℃ compared with the set temperature.
