A ball valve is a type of valve that uses a hollow, perforated, and pivoting ball to control the flow of a fluid or gas. The ball is typically made of metal and has a hole drilled through it, which lines up with the flow of the fluid when the valve is open, and is perpendicular to the flow when the valve is closed. Ball valves are often used in industrial settings, as well as in plumbing and natural gas pipelines. They are easy to operate and can be used for both on/off control and throttling purposes. The full bore and reduced bore are the two common types of ball valve.
Socket ball valves, flanged ball valves, and worm-gear ball valves are all types of ball valves that are used for specific applications.
A socket ball valve is a type of ball valve that has a socket connection. This connection type is typically used for smaller-diameter pipes and allows for easy installation and removal of the valve.
A flanged ball valve is a type of ball valve that has a flange connection. This connection type is typically used for larger-diameter pipes and allows for easy installation and removal of the valve. It also allows for a better seal and can handle higher pressure and temperature compared to socket connection.
A worm-gear ball valve is a type of ball valve that is operated by a worm gear drive. This allows for precise control of the valve position and is typically used in applications where precise control is important, such as in industrial process control. The worm gear drive can be manual or motorized.
All of these valves have a ball inside that rotates to control the flow of fluid through the pipe, and they can be used to shut off or regulate the flow of fluid or gas.
