1、[Wide Range] Enjoy water temperature from 20 to 50℃ with this water mixing valve, which has built in check valve, effectively prevents the flow of hot and cold water. 2、[Safety Locking] Our thermostatic mixing valve sets the safety button to a comfortable 38℃, and after unlocking, the temperature can be easily adjusted. 3、[Reliable Design] In the event of an unexpected loss of cold or hot water supply, the mixed outlet flow rapidly decreases and shuts down, providing protection. 4、[Fast and Accurate] Can achieve the temperature you need within 5 seconds after the water is discharged, with fluctuations within ±1℃. 5、[Stable Outlet] Ensure that the outlet temperature is constant and not affected by changes in water temperature, flow rate, and water pressure, solving the problem of intermittent hot and cold water during bathing. 1 x Thermostatic Mixing Valve Item Type: Thermostatic Mixing ValveMaterial: BrassInterface: G1/2 Inch (DN15)Working Water Pressure: 0.1- 0.5MPa (including cold and hot water pressure). It is recommended to use a working water pressure of 0.3MPa. If the working water pressure exceeds 0.5MPa, please install a pressure reducing valve on the pipeline. If the working water pressure of the drop type solar energy is lower than 0.1MPa, it is recommended to install a booster pump on the pipeline.Constant Temperature Water Outlet Temperature: 20-50℃Water Supply Temperature: Hot Water Temperature: 55-80℃ (recommended 65℃)Cold Water Temperature: 5-29℃ (recommended 15℃)
