Guillotines provide a mechanized means of inserting a duct blanking plate and offer superior isolation of flue gas applications containing heavy particulate loads and are ideal for tight shut off applications. IFI guillotine damper, has the main function of isolation of equipment to permit inspection, maintenance, or repair in addition to process isolation. Occasionally, guillotine dampers are specified for bypass ducts, if operation requirements allow enough time for the slow-moving blade to travel across the opening. The standard guillotine model is designed for assembly to be performed in such a way that the gate slides vertically. The guillotine damper is made up of a gate which slides along metal guides, closing the conduit completely. The ends are joined to the conduits by means of flanges. The guillotine damper is normally supplied as a single part. The body of the guillotine damper can be insulated externally depending upon application requirements.
Ionfiltra’s IGR Series Square Guillotine Dampers offer reliable gas isolation for square ducts, ensuring minimal pressure loss and maximum efficiency.
Ionfiltra’s IGD Series Round Guillotine Dampers, also known as Knife Gate Valves, are engineered for reliable on/off gas isolation in industrial applications. These dampers are constructed with a robust welded assembly, designed for situations where clear, unobstructed flow and minimal pressure loss are essential.
Available in dimensions up to 2000x2000mm.
Engineered to handle temperatures up to 1000°C.
Operates effectively at pressures up to 0.5 bar (7.4 psi).
Features a bonnet to prevent atmospheric gas leakage.
Built to be reliable with options for epoxy-coated carbon steel components for enhanced longevity.
Can include inspection covers for ease of maintenance.
Offers both rising and non-rising stem options.
Customized to meet specific requirements, with flange drillings available to match international standards.
Available with pneumatic, electric, or manual actuators.
Provides the possibility of 100% sealing tightness.
Like the IGD Series, the IGR Series can be configured for bidirectional operation upon request.
In the open position, the conduit is completely unobstructed, which minimizes pressure loss across the system.
Typically installed in a vertical position, but horizontal installation is also possible. Wafer type or ButtWelding ends are available upon request.
