Brass gate valve, the gate valve, also known as a sluice valve, is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid.
The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired.
The gate faces can be parallel but are most commonly wedge-shaped.
Gate valves are primarily used to permit or prevent the flow of liquids, but typical gate valves shouldn't be used for regulating flow unless they are specifically designed for that purpose.
Because of their ability to cut through liquids, gate valves are often used in the petroleum industry.
For extremely thick fluids, a specialty valve often known as a knife gate valve is used to cut through the liquid.
On opening the gate valve, the flow path is enlarged in a highly nonlinear manner with respect to the percent of opening.
This means that the flow rate does not change evenly with stem travel.
Also, a partially open gate tends to vibrate from the fluid flow.
Most of the flow change occurs near shutoff with a relatively high fluid velocity causing gate and seat wear and eventual leakage if used to regulate flow.
Typical gate valves are designed to be fully opened or closed.
When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low friction loss.
