A ball valve is a type of valve that uses a hollow, perforated, and pivoting ball to control the flow of fluids through a pipeline. It is one of the most commonly used valves in various industries due to its versatility, reliability, and ease of operation. Here is an introduction to the key features, types, and applications of ball valves: Key Features: Ball Structure: The ball valve consists of a spherical ball with a hole (bore) through its center. The ball is positioned in the valve body and rotates 90 degrees to control the flow of fluid. When the ball's bore aligns with the pipeline, it allows the fluid to pass through. Rotating the ball 90 degrees blocks the flow by positioning the solid part of the ball against the valve body. Full Port or Reduced Port: Ball valves are available in full port or reduced port configurations. Full port valves have a bore size equal to the pipeline's inner diameter, allowing unrestricted flow. Reduced port valves have a smaller bore size, causing some flow restriction. Quarter Turn Operation: Ball valves are operated by a handle or actuator that rotates the ball 90 degrees to open or close the valve. The quarter turn operation makes ball valves quick and easy to operate. Sealing Mechanism: Ball valves use soft or metal seats to provide a tight seal when closed. Soft seats, typically made of materials such as PTFE (Polytetrafluoroethylene), provide excellent sealing capabilities and are suitable for most applications. Metal seats, made of materials like stainless steel, are used in high-pressure, high-temperature, or abrasive fluid applications. Versatility: Ball valves are suitable for a wide range of fluids, including gases, liquids, and slurries. They can handle high pressure and temperature conditions, making them suitable for demanding industrial applications.
