Why Industries Prefer Bidirectional Knife Gate Valves

Bidirectional knife gate valves differ from standard unidirectional designs due to their ability to seal effectively from both directions. This feature makes them highly suitable for pipelines where flow direction may change or where reverse pressure could occur. Their robust construction and efficient sealing system ensure reliable shut-off, even when handling:

· Slurries

· Suspensions

· Fibrous materials

· Powders

· Viscous fluids

· Wastewater and sludge

· Chemical substances

YEKE Valve’s bidirectional knife gate valves are engineered to deliver optimal performance with minimal maintenance, making them a preferred choice for engineers and procurement specialists seeking durable flow control equipment.
