Flex- Seat Guillotine Dampers
Robust isolation for demanding industrial environments
Flex-seat guillotine dampers are engineered to deliver robust isolation and shut-off capabilities in demanding industrial environments. Their design features a flat, sliding blade that traverses the ductwork to provide a tight seal, aided by a flexible seat material that ensures minimal leakage even under high differential pressures. The flexible seat accommodates thermal expansion and minor misalignments, enhancing reliability and service life in applications such as power plants, refineries, and incinerators.
Key engineering considerations include the selection of corrosion-resistant materials for both the blade and frame, as well as the integration of advanced sealing systems to maintain airtightness during operation. Actuation mechanisms—manual, pneumatic, or electric—are chosen based on application requirements for speed and automation. Additionally, innovative designs may incorporate blade edge reinforcements, wear liners, and easy-access maintenance features to ensure long-term performance and reduce downtime. Flex-seat guillotine dampers are thus well-suited for critical isolation duties, especially where safety and operational continuity are paramount.
Flex- Seat Guillotine Dampers Fit:
- Attached or linked to piping/duct flanges or directly to duct.
- Flange connections may be alignment bolted and seal welded into the duct, or provided with bolt and gasket type connections.
- Guillotine dampers typically required between 10”-24” of duct space, depending on size/application.
Flex- Seat Guillotine Damper Form :
- Flex-Seat Guillotines are used for demanding applications (high temperature/pressure/corrosion) and where 100% isolation is required.
- WGD Flat Plate Guillotines are used for general-purpose low leakage applications, with lower operating temperatures/pressures.
Flex- Seat Guillotine Dampers Function:
- Open/close applications where tight shutoff is mandatory
- Often 100% isolation required with seal air systems
- Provides “man-safe” isolation of equipment for online maintenance
Industrial Applications
Flex-seat guillotine dampers are extensively deployed across a variety of industrial sectors for critical isolation and shut-off functions. In power generation facilities, these dampers are used to isolate sections of flue gas ductwork during maintenance or emergency shutdowns, ensuring operational safety and compliance with environmental regulations. Refineries and chemical plants rely on flex-seat guillotine dampers to manage hazardous gases and vapours, providing secure containment and preventing leakage.
Incineration plants utilize these dampers to control the flow of exhaust gases and maintain airtight conditions during waste processing. Mining operations and pulp and paper mills also benefit from the robust sealing capabilities of flex-seat guillotine dampers, using them to regulate dust, fumes, and high-temperature gases within processing and ventilation systems. The adaptability and reliable performance of flex-seat guillotine dampers make them indispensable in environments where precise isolation and minimal leakage are essential for maintaining operational continuity and protecting personnel.
