A ball valve is a type of quarter-turn valve that uses a spherical disc to control the flow of fluid through it. The ball inside the valve has a hole through the center, which aligns with the flow path when the valve is open and blocks the flow when the valve is closed. Ball valves are commonly used in various industries, including oil and gas, water treatment, chemical processing, and HVAC systems.

One of the key features of ball valves is their versatility and reliability. They provide tight shut-off and are capable of handling high-pressure and high-temperature applications. Ball valves offer quick and easy operation, requiring only a quarter turn of the handle to open or close the valve completely. Additionally, ball valves are resistant to contamination and are suitable for use in corrosive environments. Their simple design and low maintenance requirements make them a preferred choice for many industrial applications.
