Product Overview

The Bevel Gear Knife Gate Valve is a heavy-duty shut-off valve specifically engineered for handling thick, viscous, and solid-laden fluids. Its defining feature is the sharp-edged gate that slices through media such as pulp, slurry, ash, or wastewater with minimal flow restriction. Operated via a bevel gear mechanism, it provides smooth and controlled manual operation—ideal for large-diameter or high-torque applications.

Constructed with a corrosion-resistant stainless steel stem and gate (typically 2Cr13), and a durable WCB or stainless steel valve body, the valve is built to perform reliably under demanding industrial conditions. The sealing surface is available in a range of materials, including PTFE and hard alloy, to meet diverse media and temperature requirements. The robust gear design ensures reduced operator effort, precise control, and long service life.

Specification Applications

  • Pulp & Paper Industry: For controlling pulp flow in stock preparation and chemical recovery systems.
  • Wastewater Treatment: For sludge isolation, sediment flow control, and clarifier bypasses.
  • Mining & Mineral Processing: Ideal for handling abrasive slurries, tailings, and thick media.
  • Power Plants: Used in ash handling systems and cooling water pipelines.
  • Chemical & Petrochemical Plants: For viscous or corrosive process media requiring clean shutoff.
  • Food & Beverage (heavy-duty systems): Where hygienic, high-viscosity control is needed.
