Wahlcometroflex Announces Flex-Seat(TM) Guillotine Damper
High-Performance Damper Provides 100 Percent Gas Isolation
WahlcoMetroflex, a worldwide leader in the design and manufacture of dampers, expansion joints and systems for isolating and controlling gas flows, announces its Flex-Seat(TM) guillotine damper for the isolation of gas flows in the most extreme operating conditions. This fully bonneted guillotine damper provides high performance and simplified maintenance to meet the needs of combustion and hot gas systems of all kinds, including power plants, refineries, chemical plants, pulp and paper mills, metallurgical smelters, steel mills and incinerators.
Self-cleaning and maintenance-free rack and pinion drives provide reliable blade transfer even under the most corrosive and debris-laden service conditions. The rack and pinion drives positively propel the blade in both directions, eliminating the possibility of mechanical binding that often occurs with chain driven mechanisms.
WahlcoMetroflex's Flex-Seat guillotine damper achieves 100 percent isolation by utilizing a complete system of complementary and redundant seals. The perimeter seal consists of a resilient flexible metal seal covering a solid convex seating surface that provides a back up seal. The solid seat significantly extends the life of the flexible metal seal by limiting seal deflection to less than an eighth of an inch.
The Flex-Seat perimeter seals are self-cleaning and durable and do not have cavities that can fill up with debris. Any ash or debris on the flexible seals readily springs off when the seals are engaged by the moving blade. Tight-closing, self-cleaning throat seals are available in internally and externally replaceable configurations to facilitate replacement in hard to reach locations without scaffolding or special platforms.
The WahlcoMetroflex engineered blade consists of structural frame and reinforced metal membranes that minimize thermal distortion and provide superior sealing and operational performance compared to solid plate designs.
