3. Ball Valves. As the name suggests, ball valves are valves that use a ball to control the flow of substances from one opening to the next. These valves work by allowing the hole to be open, blocked, or open partially to regulate the flow of gas/liquid. Ball valves are the ideal choice for using with gases as they are able to offer better sealing.
A ball valve consists of a valve body in which a large sphere with a central hole equal to the inside diameter of the pipe is mounted. As the ball is rotated, in the fully open position the valve provides the through conduit or full bore required for unrestricted flow of the fluid and scrapers or pigs.

Check Valves—Also known as a nonreturn valve, check valves constantly keep the flow of fluid in onedirection to stop backflow in the piping. A major advantage with check valves is that they can be operated automatically. Check valves come in many different forms. However, the most common types are swing check valves and ball check valves.
A ball valve is a form of quarterturn valve which uses a hollow, perforated and pivoting ball to control flow through it. It is open when the ball''s hole is in line with the flow and closed when it is pivoted 90degrees by the valve handle. The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve''s status.
