Ball Control Valves

A ball control valve is a type of valve that is used to regulate the flow of liquids and gases. It is a quarter-turn valve, meaning that it is opened and closed by turning the valve handle a quarter of a turn. The valve is opened by turning the handle clockwise and closed by turning it counterclockwise. The ball control valve is composed of a ball, which is connected to the valve handle, and a seat, which is connected to the valve body. When the valve is opened, the ball is pushed up against the seat, allowing the flow of the liquid or gas. When the valve is closed, the ball is pushed away from the seat, blocking the flow of the liquid or gas. Ball control valves are used in a variety of applications, such as controlling the flow of water in plumbing systems, controlling the flow of oil and gas in pipelines, and controlling the flow of air in HVAC systems. They are reliable, durable, and easy to use, making them a popular choice for many applications.
