blade sluice
A blade sluice (also known as a blade gate or knife gate valve) is a type of sliding valve used primarily for controlling the flow of liquids, slurries, or thick materials in pipelines. It consists of a flat, sharp-edged blade (or gate) that moves linearly across the flow path to open or close the passage. Key Features of a Blade Sluice: Simple Design Consists of a blade, body, and actuator (manual, pneumatic, or hydraulic). Full Bore or Reduced Port Some designs allow full flow when open, while others have a slightly restricted opening. Tight Shut-off The sharp-edged blade provides a strong seal, especially useful for viscous or abrasive media. Low Maintenance Few moving parts make it durable and easy to maintain. Bi-directional or Uni-directional Flow Some models allow flow in both directions, while others are designed for one-way sealing. Common Applications: Mining & Mineral Processing Handling slurries, tailings, and abrasive fluids. Wastewater Treatment Controlling sludge and thick liquids. Pulp & Paper Industry Managing fibrous and viscous materials. Chemical Processing Handling corrosive or high-purity fluids. Food & Beverage Used in hygienic applications where easy cleaning is required. Advantages: Excellent for thick or abrasive fluids Minimal pressure drop when fully open Compact and lightweight compared to other valves Can be automated for remote control Disadvantages: Not ideal for high-pressure applications May wear faster with highly abrasive media Requires proper alignment to prevent leakage Types of Blade Sluices: Manual Blade Gate Valve Operated by a handwheel or lever. Pneumatic or Hydraulic Actuated For automated control. Lined Blade Valve Has a rubber or polymer lining for corrosion/abrasion resistance. Would you like details on a specific type or application?

The new raid content is fantastic with challenging mechanics. However, there are still some bugs that need to be ironed out. Overall a solid expansion that keeps me coming back for more.
