Knife Edge Gate Valve


Description

High-Performance Knife Edge Gate Valves

FlowBiz is a premier manufacturer of Knife Edge Gate Valves in India, offering high-durability solutions for both unidirectional and bidirectional flow control. Our valves are specifically engineered to provide a trusted shutoff in the most challenging environments, handling everything from wet slurries to dry solids.

Equipped with a heavy-duty, sharpened gate, our bonnet-less design is purpose-built to cut through thick sediments, abrasive slurries, and semi-solids where traditional gate valves often fail to seat.

Engineering Excellence & Design

FlowBiz Knife Edge Gate Valves utilize a precision-ground "knife" edge to clear impediments in the flow path during closure.

  • Cutting-Edge Technology: The sharp bottom edge of the gate slices through solid residues, ensuring a tight seal against the resilient seat.
  • Versatile Seating: Available with Metallic or Resilient (Soft) seats to match your specific pressure and media requirements.
  • Lightweight & Compact: Our wafer and lugged designs are significantly lighter than standard gate valves, making them easier to install, maintain, and automate.
  • Material Options: We maintain a ready stock of Mild Steel (MS)Stainless Steel (SS), and Cast Iron (CI) Knife Gate Valves.
