Select and buy a ball valve online for your application. Ball valves are used to control the flow of a media, liquid or gas, by means of a rotating ball with a bore. They are also called shut off valves, as they can effectively stop the media flow through the system. They are one of the most common valves due to their simple operation, reliability, long service life, and wide range of application uses. They can be manually operated or operated with an electric or pneumatic actuator for remote or automated operation. Depending on your application and available electrical/pneumatical input, you can select the proper ball valve for your application.
