Application & Function
Gate valves are primarily used for stop valves fully opened or fully closed and are not normally considered for throttling purposes, but more for slurries, viscous fluids, etc. Gate valves are characterized by a traveling wedge that travels perpendicular to the direction of flow. Gate valves usually have a minimum pressure drop when fully open, provide tight shut-off when fully closed, and remain relatively free of contamination buildup.
