The water output is flexibly controlled by rotating the valve core. The cold valve ensures the daily supply of cold water, while the hot valve is suitable for hot water scenarios, meeting different water usage demands. It is equipped with an anti-backflow function to prevent water backflow caused by reverse pressure in the pipeline. At the same time, it can quickly close and cut off the waterway, facilitating equipment maintenance and reducing water leakage losses. The design is optimized for the difference in hot and cold water pressure. The hot valve can withstand high temperature and high pressure, while the cold valve is suitable for normal temperature water flow. Both can operate stably and avoid the influence of water pressure fluctuations.
