Which type of valve has the greatest capability to handle slurries and fluids with high suspended solids?

The ball valve is known for its ability to handle slurries and fluids with high suspended solids effectively. This capability largely comes from its design, which features a spherical disc that rotates to control fluid flow. This allows for a relatively unobstructed passage through the valve when fully open, reducing the risk of clogging that can occur with other valve types, such as globe or needle valves that have more restrictive flow paths.

Additionally, ball valves usually have a larger cross-sectional area compared to other valve types, facilitating the movement of slurries that may contain solid particles. Their robust construction can also withstand the erosive nature of abrasive materials present in many slurries. Therefore, when dealing with challenging fluids that contain considerable amounts of solids, ball valves are often the preferred choice due to their design and operational efficiency.
