Gate Valve

Definition

A valve utilizing a wedge-shaped gate, which allows fluid flow when the gate is lifted from the seat.

Purpose

Gate valves are used to control the flow of liquids by lifting a gate out of the path of the fluid, providing a straightforward and effective means of starting or stopping flow in a pipeline.

Examples of Use

• Water Supply Systems: Used to control water flow in municipal and residential water systems.
• Oil and Gas Industry: Employed in pipelines to regulate the flow of crude oil and natural gas.
• Fire Protection Systems: Installed in fire suppression systems to control water flow.

Related Terms

• Ball Valve: A valve that uses a spherical obstruction to start or stop flow.
• Butterfly Valve: A valve that uses a rotating disc to regulate flow.
• Globe Valve: A valve that uses a linear motion to throttle flow.

Notes

Gate valves are not ideal for regulating flow but are excellent for on/off control. They should be fully opened or fully closed to prevent damage.
