The copper wall-mounted time-delay faucet combines a high-purity copper body with a time-delay water-out function, which not only has the advantage of safe water use, but also prevents waste caused by forgetting to turn off the water. It is mostly used in densely populated areas such as schools, factories, and subways. The Chinese faucet factory provides a time-delay valve core with adjustable flow and time, anti-fingerprint treatment on the shell, soft water outflow, and supports customer customization of wall-mounted bases and connection threads. It is an engineering-grade product that emphasizes both durability and aesthetics.
