Cavity Pressure Relief Seat
Ball Valve Used in the Oil and Gas Industry
There are a number of different processes that take place inside and oil and gas factory. Each of those processes requires different kinds of materials to be taken to and from machinery and equipment. This means a number of different kinds of valves are needed for a single process to be successfully completed.
Ball valves are quarter-turn valves that provide quick shut-off and turn-on operation. These valves feature a sphere or a ball with a hollow center. When the center aligns with the pipe, the valve is open and allows the flow of the medium. When the ball turns, the center is no longer aligned with the pipe and the flow stops.
The stem and ball of these valves are usually made of some kind of metal while the seat is made of soft materials like Teflon. This combination of materials helps the ball valves work in temperatures as low as -200 degrees Centigrade and as high as 500 degrees Centigrade. Ball valves are very versatile and can be used to regulate the flow of liquids, gasses, and air. They are very famous in the industry because they provide a tight seal and a low torque. The only con of using ball valves is that they can only be used for shut-off applications, they cannot be used for throttling.
