Angle stop valves, also known as angle valves or stop valves, are plumbing fixtures that are typically used to control the flow of water in a plumbing system. They are installed at the point where a supply line branches off from the main water line, and are often used to control the flow of water to individual fixtures such as sinks, toilets, and washing machines.
An angle stop valve typically consists of a valve body, a handle, and a stem. The valve body is connected to the water supply line, and the stem is connected to the handle. The handle is used to control the flow of water by turning the stem, which opens or closes the valve.
The most common type of angle stop valves are quarter-turn valves, which are designed to be turned 90 degrees to control the flow of water. They are made of different types of materials, including brass, chrome, and plastic.
Angle stop valves are commonly used in residential and commercial plumbing systems, and are typically installed by a plumber. They are a essential part of the plumbing system.
