Flex-Seat

The Flex-Seat fully bonneted guillotine damper is designed for the isolation of gas flows in the most extreme operating conditions. It 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 enable reliable blade transfer even under the most corrosive and debris-laden service conditions. The Flex-Seat’s guillotine damper achieves 100% isolation by utilizing a system of complementary and redundant seals. The perimeter seal consists of a flexible metal seal covering a solid convex seating surface, which provides a back-up seal. The solid seat significantly extends the life of the flexible metal seal by limiting seal deflection to less than 0.125 in.
