What is a Lug Type Knife Gate Valve?

A lug type knife gate valve features a unique design. It has a flat body with a gate that slides up and down. This movement allows materials to pass through easily. The “lug” design enables the valve to be bolted directly to the pipeline. No additional flanges are needed. This makes installation easier.

Key Features of Lug Type Knife Gate Valves

  • Durability: These valves are built to last. They can handle tough conditions and high pressures.
  • Versatility: You can use them in various industries like wastewater, pulp and paper, or mining.
  • Easy Maintenance: The design allows for quick maintenance and repairs without removing the valve from the pipeline.
  • Effective Sealing: They provide a tight seal, preventing leaks.

How Does It Work?

Let’s break it down. Imagine you have a pipeline filled with a thick slurry. You need to stop the flow to service the system. Here’s where the lug type knife gate valve comes in. When you close the valve, the gate moves down into the pipeline. This creates a barrier, stopping the flow. When you need to restart the flow, simply lift the gate back up.
