Simple design: Consists of a gate that moves perpendicular to the flow direction. Low pressure drop: When fully open, there's minimal obstruction, resulting in low resistance to flow. Slow operation: Due to the gate's movement, it takes multiple turns to open or close completely.
Parallel gate valves: The gate faces are parallel.
Wedge gate valves: The gate is wedge-shaped for better sealing.
Double disc gate valves: Two discs are used for better sealing and reduced wear.
