Wafer Type Damper Valve

Butterfly-type Damper Valve Manufacturer: FlowBiz Exports

The FlowBiz Damper Valve operates using a standard butterfly mechanism, featuring a disc that rotates $90^{\circ}$ within the duct. Unlike high-pressure liquid valves, dampers are optimized for gas streams. They are the ideal choice for flue-gas scrubbers and ventilation systems where a small amount of leakage (approx. 5%) is permissible in exchange for rapid actuation and reduced weight.

Key Features & Advantages

  • Lightweight Design: Constructed to minimize the load on large-diameter ductwork, making installation faster and less labor-intensive.
  • Rapid Actuation: The drive mechanism is remarkably simple, requiring only a quarter-turn to move from fully open to fully closed.
  • Cost-Efficient: Because they do not require complex resilient seating for bubble-tightness, damper valves are an inexpensive alternative for air-based applications.
  • Durable in Harsh Gas Streams: Available in various grades of Stainless Steel to withstand corrosive flue gases and high-temperature industrial exhaust.
  • Versatile Mounting: Often used as isolating dampers in scrubber units, where they prevent the backflow of gases during maintenance or process changes.
