Knife Gate Valves for Slurry: How Fluidtecq Keeps Tough Industries Flowing with Abrasion-Resistant Design.

When your plant handles slurry, sludge, or fibrous media, ordinary valves don't just struggle—they fail, leak, and shut your process down. Knife Gate Valves (KGVs) are engineered specifically for these harsh duties, and Fluidtecq's slurry-ready KGVs give mining, wastewater, pulp & paper, power, and chemical plants a reliable way to cut through the problem.

The Slurry Problem: Why Conventional Valves Fail

Slurry systems carry a mix of liquid and abrasive solid particles that grind, erode, and pack into every cavity they can find.

Gate, globe, or butterfly valves designed for clean media quickly suffer:

• Erosion: Abrasive particles damage soft seats and valve internals.
• Jams & Clogs: Solids and fibrous material pack into the valve body and seating areas.
• Leakage: Damaged seats lead to poor isolation, safety hazards, and product loss.

The result is rising maintenance costs, frequent valve replacement, and unplanned shutdowns that hit throughput and safety.

What Makes a Knife Gate Valve Different?

A Knife Gate Valve is the industry's solution for solid-laden media.

• The Cutting Edge: KGVs use a sharp-edged gate that slides down through the flow, literally cutting through solids, fibres, and settled deposits.
• Full Bore Flow: Their full, straight-through bore and minimal internal cavities allow slurries and semi-solids to pass with less risk of clogging or pressure build-up.
• Compact Design: Many designs offer bi-directional sealing and compact face-to-face dimensions (Wafer Type), which helps OEMs and end users save space while maintaining reliable isolation.

Industries That Depend on Slurry-Ready KGVs

Across several industries, knife gate valves have become the go-to choice wherever media is thick, abrasive, or full of solids. Typical high-duty applications include:

• Mining and Mineral Processing: Ore slurry, tailings, cyclone feed, and concentrate lines.
• Wastewater and Sewage Treatment: Sludge, grit-bearing wastewater, dewatering lines, and digester feeds.
• Pulp and Paper: Fibrous stock, recycled pulp, black liquor, and recovery applications.
• Power and Ash Handling: Fly ash and bed ash in thermal power plants and cement/boiler systems.
• Chemical and Process Plants: Viscous, corrosive, or solid-laden process streams.

In all these environments, Fluidtecq's KGVs help operators maintain control and uptime where traditional valves quickly wear out.

Fluidtecq Knife Gate Valves: Engineered for Slurry and Ash

Fluidtecq designs Knife Gate Valves specifically for demanding slurry, fly ash, and pulp applications, combining robust metallurgy with proven automation.

Automation is Key: The Fluidtecq Advantage

Pneumatic actuation is a key strength. Fluidtecq manufactures its own pneumatic cylinders and rotary actuators and integrates them with matching solenoid valves (as detailed in the uploaded files). This creates a compact, factory-tested valve–actuator package that is a plug-and-play solution for OEMs and end users, ensuring the actuator is correctly sized to deliver the necessary force to shear through the solids.

How Fluidtecq KGVs Solve Typical Slurry Issues

• Mining & Erosion: We offer carefully ground stainless-steel or hard-coated gates and robust body designs. For the most abrasive lines, our sealing protect the wetted parts, drastically extending valve life and reducing emergency shutdowns.
• Wastewater & Ragging: The knife-edge design shears through stringy solids and rags. The near-full-bore path helps keep media moving, reducing the chance of blockage at the seat—a crucial feature in sludge and dewatering lines.
• Power & Ash Handling: For aggressive environments like high-temperature fly ash or bed ash, Fluidtecq offers specific high-temperature designs with suitable metallurgy and trims engineered for extreme abrasion and heat.

Next Steps: Specify Your Slurry Solution

For plants facing chronic issues with clogging, erosion, or leakage in slurry lines, upgrading to correctly engineered Knife Gate Valves is a straightforward way to improve uptime and safety.

Fluidtecq combines over 35 years of valve and automation experience with a focused portfolio. Our engineering-led approach allows OEMs and plant engineers to specify valves that last longer, operate more reliably, and integrate seamlessly with modern automation systems.
