Which type of valve is noted for its ability to handle slurries and high suspended solids?

The ball valve is particularly well-suited for handling slurries and high suspended solids due to its design. The spherical closure element within the valve creates a relatively large flow area and a smooth surface that minimizes obstruction, which is crucial when dealing with fluids containing particulates. This design helps to prevent the accumulation of solids that could lead to clogging or inefficiencies in the flow process.

Additionally, ball valves have the capability to provide a tight seal when closed, which is important for preventing leakage of slurries that can be viscous and abrasive. Their straightforward construction allows for easy maintenance, which is advantageous in systems where slurries or solids are frequently handled.

In contrast, other types of valves may not perform as well in similar conditions. For example, tapered plug valves can handle some level of particulate matter, but their design may not be as efficient as a ball valve in preventing buildup. Rising stem globe valves are generally used in throttling applications and may be prone to clogging due to their internal geometry. Lift check valves, while effective for preventing backflow, are not typically designed for applications involving slurries, as their construction is better suited for clean liquids. Hence, the ball valve stands out as the best option for these specific applications
