Knife gate valves control water flow with a thin flat plate (called a knife) that is opened and closed by pulling or pushing a T-shaped handle. Since they can be rapidly operated, they are ideal for filter drain lines that must only be opened for a few seconds. Large knife valves are often used in the bottom-drain lines feeding vortex filters and skimmer tanks.
