A directional flow accessory is used to change the direction of waterflow in a pipe. This is typically done when it becomes necessary to divert the flow of water away from areas where it could damage property or injure people. There are different types of directional flow accessories, including check valves, weir buckets, and gate valves.
These devices help to control the rate, direction, and volume of water flowing through a pipe by opening and closing depending on the conditions at hand.
