Flanged Knife Gate Valve Manufacturer in Canada
A flanged knife gate valve is a robust industrial valve designed to provide full isolation in pipelines handling slurry, viscous fluids, or solid-laden media. The flanged design ensures secure, leak-proof connections to piping systems, making it suitable for high-pressure and abrasive service lines.
SVR Global is a leading Flanged Knife Gate Valve Manufacturer and Supplier in Canada, delivering engineered valve solutions for pulp and paper, mining, wastewater, chemical, and industrial utility pipelines. Our flanged knife gate valves are designed for reliable operation, minimal maintenance, and long service life in both standard and severe-service industrial applications.
With extensive experience supporting EPC contractors, plant operators, and maintenance teams across Canada, SVR Global supplies flanged knife gate valves that meet stringent project specifications and international standards.
What Is a Flanged Knife Gate Valve?
A flanged knife gate valve is a linear motion valve that uses a sharp-edged gate to cut through solids and provide tight isolation. The flanged ends allow direct bolting to pipeline flanges, offering secure and leak-proof installation. These valves are designed to provide full shutoff in slurry, sludge, and other solid-laden media applications, preventing leakage and protecting downstream equipment.
Flanged Knife Gate Valve Applications in Industrial Systems
SVR Global flanged knife gate valves are used across a variety of industrial pipelines, including:
- Slurry pipelines in mining operations
- Pulp and paper processing lines carrying fibrous media
- Wastewater and sludge handling systems
- Chemical processing lines with viscous or abrasive fluids
- Bulk material pipelines requiring secure flanged connections
These applications require valves that can handle abrasive media, provide reliable shutoff, and maintain performance under heavy wear conditions.
Types of Flanged Knife Gate Valves
SVR Global manufactures multiple flanged knife gate valve designs to suit different process requirements:
Resilient Seated Knife Gate Valves
Provide tight sealing with elastomer-lined seats for moderately abrasive or corrosive fluids.
Metal Seated Knife Gate Valves
Used for high-temperature or highly abrasive services where seat durability is critical.
Pneumatic and Electric Actuated Knife Gate Valves
Enable automated operation for high-cycle or remote pipelines.
Rising Stem and Non-Rising Stem Designs
Support specific installation requirements while ensuring smooth gate alignment.
