1. The solid brass valve core is solid and durable, and is not easy to rust.2. The cold and hot water connection is equipped with a filter screen to protect the water from other impurities.3. The wall-mounted bathtub thermostatic mixing valve is easy to install and is applicable to most .4. It is easy to control the cold and hot water volume and adjust the water temperature as required.5. Built-in temperature control safety device can automatically turn off hot water without cold water to protect scalds.The thermostatic water mixing valve is a supporting product specially developed for hot water . It is widely used in electric , pipe water valves, washbasins, bidets, shower solar and centralized heating water . It can also be applied to electric and solar . Users can adjust the mixing temperature of cold and hot water according to their needs. The required temperature can be quickly reached and stabilized to that the outlet temperature is constant and not affected by the changes in water temperature, flow and water pressure. It can solve the problem of sudden cold and hot water temperature in the bath. When the cold water is interrupted, the mixing valve can automatically the hot water within a few seconds, playing a role of safety protectionWorking pressure: 0.05-mpaRecommended pressure: 0.1-0.5 mpa (pressure above 0.5 mpa requires relief valve)Standard pressure: dynamic pressure 0.3 0.02 mpaCold water supply temperature: 4 C-29 CHot water supply temperature: 55 C-85 CRecommended normal use temperature: 60-70 CWater temperature control range: 20 C-50 CSafety button temperature: 38 CColour:gold+silverMaterial:MetalPackage Contents:1 x Thermostatic pipeline valveOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing.
