Valves for media containing suspended particles are suitable for those with a closure that slides along the sealing surface with an abrasive action. If the closure's movement against the valve seat is vertical, particles may become trapped, so such valves are only appropriate for media that is essentially clean unless the sealing surface material can accommodate embedded particles. High-temperature butterfly valves and plug valves have an abrasive action on the sealing surface during their opening and closing process, making them suitable for use with media containing suspended particles. Valves are typically chosen for controlling flow based on their ease of adjusting the flow rate. Downward-closing valves (such as gate valves) are suitable for this purpose due to the proportional relationship between the valve seat size and the stroke of the closure. Rotational valves (plug valves, butterfly valves, ball valves) and flexible body valves (clamshell valves, diaphragm valves) can also be used for throttling control, but usually only within a limited range of valve port sizes.
