Description

UNI-FLO QM Knife Gate Valve

The UNI-FLO QM Knife Gate Valve is designed for reliable isolation in demanding slurry, wastewater, and solid-laden applications. Built for durability and performance, it provides efficient shut-off while preventing material build-up inside the valve body.

Its robust design ensures long service life in harsh industrial environments such as mining, power generation, and process industries where abrasive and viscous media are common.

Key Features

  • Bi-directional sealing for reliable shut-off in both flow directions
  • Full bore design for unrestricted flow
  • No grooves or cavities in the bore, preventing slurry accumulation
  • Self-cleaning flush-out corners to prevent deposit build-up
  • Fully moulded and reinforced body seal to prevent creep and reduce operating torque
  • Precision-machined stuffing box cavity for improved sealing efficiency and reduced torque
  • Arched PTFE scrapers across the blade width for effective cleaning action
  • Low maintenance and high durability design

Pressure Ratings

  • DN50 – DN200: Up to 16 bar
  • DN250 – DN600: Up to 10 bar

Standards & Design Benefits

  • Engineered for heavy-duty slurry and abrasive service
  • Optimised sealing system for reduced wear and extended service life
  • Designed for efficient operation with lower opening and closing torque

Applications

  • Mining and mineral processing
  • Slurry and tailings systems
  • Wastewater treatment plants
  • Power stations
  • Bulk solids and industrial process lines
