A ball valve is a tube that allows fluid to flow through it. They are available in a wide variety of shapes, sizes, and materials. However, choosing the right one can be difficult.
Ball valves are commonly made from stainless steel. This material has positive attributes, including being corrosion resistant and durable. This means they're an excellent choice for a variety of geochemical and general plant systems. The resulting valves are ideal for fluids that have high concentrations of solids. This also means that they're great for slurries.
A ball valve is not suitable for all applications. Fluids that contain abrasive solids in suspension or fibrous materials may be clogged in the valve, increasing operating torque and rendering the valve inoperable. Some ball valves can also cause water hammer if the valve body is not vented. In addition, fluids containing abrasive solids can damage the ball's surface. This makes it difficult to clean.
Ball valves are best used in on/off service. These valves use a ball-shaped seating element that requires a quarter-turn opening for the valve to function properly. They also require manual or power operators when operating at high operating pressures. They also have soft seats and a metal-to-meal secondary seal. Their biggest drawback is that they can be fragile, especially if there is a large pressure drop across the ball.
Ball valves come in two-piece and three-piece designs. One piece is the valve body and the second piece holds the trim in place. The two-piece version is usually easier to clean than the three-piece design. However, a three-piece ball valve is often more expensive and difficult to service, so be sure to research all your options before choosing a ball valve.
Compared to other types of valves, ball valves have a long life cycle. Ball valves are typically used as shut-off valves and are resistant to contaminated media. They can also be operated manually or with an actuator. Another common type is the ball check valve, which uses a solid ball for backward flow prevention.
When choosing a ball valve, it's important to consider the number of ports it has. A full-port ball valve has an inner diameter that matches the pipe that it's connecting to. This ensures that the flow will not be restricted by a tight inner-port. In addition, a full-port ball valve will have a lower pressure drop than a standard port valve.
