The gate that controls a sluice is a valve known as a “sluice gate.” These valves are designed to seal in one direction and commonly are used to control water levels and flow rates in rivers and canals. They also are used in wastewater treatment plants. A sluice gate can be one of several different types of valves that may have different names in any given industry. The most common type is a vertical rising sluice gate valve. This valve has a gate that rises (to allow fluid to flow under it) and lowers (to stop the flow.) If fluid can flow over the top of a sluice gate when it is closed, the gate is known as a weir gate. Sluice gates can have round, square or rectangular gates/openings.
