Gate Valves are widely used in fluid-handing systems for flow control, 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.
Available in large sizes.
Can be used with slurries and viscous liquids.
Used as a shut off valve.
Easy to maintain and disassemble.
Inherently fire-safe (when used with a metal sheet).
