What is a scour valve?
Scour valves are located at low points or between valved sections of the pipeline. Their function is to allow periodic flushing of the lines to remove sediment and to allow the line to be drained for maintenance and repair work.
Is a scour valve a Gate Valve?
Sluice Valve and/or Gate Valve functions strictly to either start or stop the flow. Gate valves are used for water supply system and sluice valves are used for slurries. Gate valve is opened by lifting gate/wedge from the flow of water, allowing all water to pass without resistance.
What is scour water?

What is Swiss gate?
A sluice gate is traditionally a wood or metal barrier sliding in grooves that are set in the sides of the waterway and can be considered as a bottom opening in a wall. Sluice gates are one of the most common hydraulic structures in controlling flow rate and water level in open channels such as rivers and canals.
What is Sluiceway in dam?
: an artificial channel into which water is let by a sluice.

What is nominal pressure rating?
nominal pressure (PN) : A numerical designation relating to pressure that is a convenient round number for reference purposes. It is intended that all equipment of the same nominal size (DN) designated by the same PN number shall have the same mating dimensions appropriate to the type of end connections.
Why are valves used?
Valves provide several functions, including: Starting or stopping flow based on the valve state. Regulating flow and pressure within a piping system. Controlling the direction of flow within a piping system. Throttling flow rates within a piping system.
