Therefore, end users needing to modulate slurry flow must select alternate valves with simple ‘line of sight’ designs, such as ball valves, butterfly valves and pinch valves
. These designs provide relatively little flow re-direction and minimal interference with the abrasive slurry. The downside is that fluid velocities through these types of valves are much greater, making them susceptible to cavitation
. The flow is also directed towards the valve’s body and pipe wall.
