Dampers for control and isolation of flue gas
The Senior Flexonics Pathway family of damper products include guillotines with a variety of drive modes including the patented Blade Drive concept, single and double louvers, butterfly dampers, diverter valves for gas turbines and other industrial applications, and poppet valves for bag house internals. Materials of construction include carbon and alloy steels, stainless steel, and high nickel alloys.

Operating times range from 1/2 to 1 sec. for louvers, 1 sec. for butterflies, and 10 sec min and are size dependant for guillotines.

|
Louver dampers are more costly than butterflies but less than guillotines.
|
|

|
Static pressure loss is minimal with guillotine dampers and greatest with louver dampers.
|
|
·
|
Louver dampers are available in parallel or opposed blade configurations for improved flow control where sealing efficiency is important but improved control is also desired.

GUILLOTINE DAMPERS
WahlcoMetroflex guillotine dampers are available in three basic configurations to meet a wide range of applications. For severe applications, WahlcoMetroflex offers a line of fully bonneted guillotines. Many customers favor the “Flex-Seat™” and “Thrust-Seat™” premium designs for applications where extreme operating conditions are encountered and high performance is required.
“WGD™” guillotine dampers are designed for general applications and simplified maintenance. They incorporate a cost effective, single thickness, solid plate blade and many features facilitating maintenance such as self-cleaning drives and seal elements accessible from outside the ductwork.
WahlcoMetroflex guillotine units incorporate self-cleaning rack and pinion drives which positively drive the blade in both directions without the
