Knife Gate Valves: The Ultimate Solution for Slurry and High-Solid Isolation

A Knife Gate Valve is a specialized linear-motion valve designed specifically for systems with high concentrations of dissolved solids, abrasive particles, or fibrous materials. At FlowBiz Exports, our knife edge design is crafted to "cut" through the media to ensure a complete shut-off.

How Does a Knife Gate Valve Work?

The primary feature of this valve is the sharp-edged, beveled gate (the "knife").

  1. Cutting Action: As the valve closes, the sharpened bottom of the gate slices through slurries, pulp, or heavy liquids to reach the seat.
  2. Full Bore Flow: When fully open, the valve provides a completely unobstructed flow path, ensuring a minimal pressure drop and maximum flow efficiency.
  3. Self-Cleaning: The motion of the gate pushes particles away from the seating area during operation, preventing clogging and buildup.

Key Features of FlowBiz Knife Gate Valves

  • Debris-Free Design: Unlike standard gate valves, our KGVs have no "pocket" or grooves at the bottom of the body where solids can collect and prevent the valve from closing.
  • Lightweight & Compact: The narrow "face-to-face" dimension makes them much lighter and easier to install in tight piping systems compared to bulky wedge gate valves.
  • Replaceable Packing Gland: For easier maintenance, the packing gland is usually replaceable without the need to disassemble the entire valve from the line.
  • High Viscosity Compatibility: Whether it is thick sludge, abrasive mine tailings, or corrosive chemicals, our valves allow any viscosity to pass through smoothly.
