A gate valve, also known as a sluice valve, is a valve that opens by lifting a round or rectangular gate or 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 restric¬tion is desired. The gate faces can form a wedge shape or they can be parallel. Most of the flow change occurs near shutoff with a relatively high fluid velocity causing disk and seat wear and eventual leakage if used to regulate flow.

Gate valves are characterized as having either a rising or a nonrising stem. They may have flanged ends which are drilled according to pipeline compatible flange dimensional standards. A gate valve is typically constructed from cast iron, ductile iron, cast carbon steel, gun metal, stainless steel, alloy steels, and forged steels.
