Butterfly Dampers
Get Price Quote
The butterfly or wafer damper can be a stack damper where leakage is not all-important. This type has also been tried as an isolating damper for flue-gas scrubbers. The butterfly damper is lightweight, simple, quickly actuated, and often comparatively low in cost. Its frame shape is a handicap in power plant work, however, where much ducting is rectangular. In process work, oval shapes adapt to that shape of duct, but conversion of a round butterfly to a rectangular one results in a louver damper. Occasionally, a double-disc butterfly appears, resembling a circular two-bladed louver damper.Disadvantages of the butterfly damper include high leakage, blade flutter, tendency of the blade to warp, and large clearance needs for the open blade. The frame of most butterfly dampers is light, so twisting and distortion are dangers.Most butterfly blades or discs are flat and single-thickness, so reinforcement is necessary for pressurized duct service. Either angles or simple bars on edge will stiffen the plate. Welding of the reinforcing can warp the plate badly, requiring straightening. Another disadvantage of reinforcing is the flow resistance it causes when the damper is open. Seals for the butterfly damper are usually simple, either flat metal-on-metal, or a soft seat resembling a tadpole gasket.

Pressure relief dampers should be provided in each room to prevent contamination of air from clean and dirty areas. Suitably sized air pressure relief damper should be strategically placed, enabling differential room pressure to be maintained and ensure that when doors are opened between clean and dirty areas. Counter- weight balancing system should be provided in the PRD to maintain positive pressure inside the operation room. Air pressure stabilizers should have unique capability of controlling differential pressure to close tolerance. The PRD should remain closed at pressure below the set pressure and should open fully at pressure and should open fully at pressure only fractionally above the threshold pressure. The body should be epoxy powder coated as per standard BS colors. First class electrolyzed steel plate should be used for body and with high grade SS304 stainless steel for blades.
