Square Knife Gate Valve KGSQ – Robust, Versatile, and High-Performance

Flowrates‘ welded square section knife gate valves are specifically designed for the precise control of solids, powders, and bulk materials. Their unobstructed flow design ensures smooth and continuous discharge, reducing material build-up and premature wear. The welded steel construction provides exceptional strength and durability, making them ideal for the most demanding industrial conditions.

Welded Construction for Industrial Tightness and Durability

  • Unrestricted flow: No cavities or obstructions, ensuring smooth discharge and complete evacuation of solids.
  • Heavy-duty welded construction: Engineered for extreme mechanical and abrasive conditions.
  • Wide range of sealing materials – Elastomers, PTFE with dynamic seals, or metallic seats with compensation systems for tight shutoff, even at high temperatures and pressures.
  • Bonneted version available: Maximum fluid containment for sensitive applications requiring full isolation from the atmosphere.

Industrial Applications of the Square KGSQ Valve

  • Energy & Environment – Incineration, biomass, and ash handling
  • Food Industry – Transport and dosing of powders and granules
  • Mining – Management of ores and solid residues
  • Cement & Quarries – Handling and dosing of cement, lime, and silica
  • Pulp & Paper – Fiber control and slurry handling
  • Chemical Industry – Transport of fine powders and granulated materials

With their rugged design and ability to handle severe operating conditions, Flowrates‘ welded square section knife gate valves are the ultimate solution for industries requiring performance, reliability, and long-term durability.
