Max angle valve is a type of plumbing valve that is used to control the flow of water in a pipe. It is typically installed at the point where the pipe changes direction, such as at a corner or elbow, and is designed to allow for a maximum angle of turn. Max angle valves are available in various sizes and configurations, including threaded, compression, and push-fit connections, to accommodate different types of pipes and plumbing systems. They can also come in different materials, such as brass, chrome-plated brass, or stainless steel, to provide durability and resistance to corrosion. When installing a max angle valve, it's important to ensure that the valve is properly aligned and tightened to prevent leaks. It's also important to choose the correct size and type of valve for the specific application, as well as follow the manufacturer's instructions for installation and operation.
