The Advantages of a Sharp 
Design
● Superior Shutoff (positive closure for viscous fluids/solids)
● Accommodating Tough Media (handling slurries, viscous fluids, 
some semi-solids)
● Easy Maintenance (simple design, facilitates cleaning)
● Durability and Versatility (robust construction, various 
materials/sizes)
Applications: Where the Knife Gate 
Shines Industries That Benefit from Knife Edge Gate Valves
Chemical Processing (isolating equipment, handling corrosive fluids)
Wastewater Treatment (solids handling, isolating sections)
Food and Beverage Production (sanitary designs for food-grade 
materials)
Pulp and Paper Production (thick slurries, fibrous materials)
Considerations When Choosing a 
Knife Edge Gate Valve
Media Compatibility (material selection for corrosion resistance.
Pressure and Temperature Ratings (exceeding operating conditions)
Actuation Mechanism (manual, gear, or automated based on needs)
Flow Rate Requirements (sufficient flow capacity for your application)
Conclusion
By understanding their strengths and limitations, you 
can leverage the power of knife edge gate valves to 
optimize your industrial processes.
