Pneumatic Unidirectional Knife Gate Valve

Middleeast Valve is a trusted manufacturer and exporter of industrial valves. We provide high performance flow control products. Our most reliable product include the Pneumatic Unidirectional Knife Gate Valve, specifically designed for use in harsh application involving thick fluid, slurry and solid loaded media where unidirectional flow and tight shut off are required.

 Definition

Pneumatic Unidirectional Knife Gate Valve is a valve utilizing a sharp edge gate to cut through media and control flow in one direction. Powered by a pneumatic actuator, it provides accurate and automatic control, making it the best for troublesome-to-handle material.

 Major Components

  1. Pneumatic Actuator: Utilize compressed air to automatically raise or lower the gate.
  2. Knife Gate: A blade with sharp edge used to cut through solid or semi solid media.
  3. Body: Typically constructed of stainless steel or cast iron designed for abrasion and corrosion resistance.
  4. Seat and Seal: Provides close shut-off in one direction of flow.
  5. Stem and Packing: Links actuator to gate, with sealing to avoid leakage.

 Working Mechanism

With applied pneumatic pressure, the gate is pushed by the actuator up or down. The gate travels perpendicular to the flow and opens or closes the valve. Unidirectional design prevents one-way leakage by controlling flow in one direction only.

 Advantages

  • Best for slurry, pulp, powder, and waste media
  • Self-cleaning gate minimizes clogging
  • Small and light body
  • Pneumatic operation supports remote control
  • Low maintenance necessary

 Industries Applicable in:

  1. Mining and mineral processing
  2. Wastewater treatment
  3. Pulp and paper
  4. Power plants
  5. Chemical industries

 Why is it Necessary?

For the use of abrasive or viscous materials, a typical valve could clog or fail. A Pneumatic Unidirectional Knife Gate Valve provides smooth and reliable shut-off and control in such tough applications.
