The stop valve angle valve produced by the Chinese faucet factory is often made of brass or stainless steel, with a chrome-plated or brushed surface treatment that is both aesthetically pleasing and durable. Its main function is to control water flow. When equipment needs maintenance or replacement, the entire home's main valve does not need to be shut off—just close this angle valve. It is usually installed at the water inlet of faucets or bathroom equipment. Make sure the valve switch is positioned for easy operation.
