A gate valve, also called a sluice valve, is a type of industrial valve that opens by raising a barrier (gate or disk) out of the fluid’s path, allowing the fluid to flow in a pipeline; and closes by lowering a barrier (gate) that results in preventing the fluid from flowing. All the movements applied for the gate to be lifted or lowered are in the direction perpendicular to the fluid flow. Gate valves take up very little space along the pipe axis and barely hinder fluid flow when wholly opened. These valves should not be used to regulate flow; they should be utilized completely open or fully closed. In other words, this type of valve is in the category of on-off valves and will be damaged in the partial opening state.

The gate sides can be generally divided to parallel or wedge-shaped, but they are most typically wedge-shaped in order to be able to exert pressure on the sealing surface. The straight-through, unobstructed path of a gate valve is its distinguishing feature, resulting in minimal pressure loss across the valve. Unlike butterfly valves, the unobstructed bore of a gate valve allows for pig passage during cleaning.
