FORENSERVTEK diverters are used to direct gas flow between the main process and bypass. Mechanical interlocks ensure the two valves operate in an open-closed sequence, safeguarding system safety. These dampers can be applied for both isolation and control duties.
We offer a variety of diverter damper designs:
●Flap diverter
●Multilouvre diverter
●Butterfly diverter
We supply a full range of fully customized diverters. Optional control panels are available with complete control functions. The inlet and bypass sections can be configured independently (including number of blades, sealing structure, bearing type, etc.).

FORENSERVTEK guillotine isolation dampers (also known as gate dampers) are suitable for all applications requiring positive isolation for routine maintenance and/or duct inlets behind media sources.
Depending on the equipment and process media conditions, we can offer either a sealed air system or a face seal design to meet your requirement for 100% process sealing under various operating conditions.
FORENSERVTEK guillotine isolation dampers are available with rectangular flanges or circular flanges for perfect adaptation to your on-site piping.

FORENSERVTEK sealed air dampers are the ideal solution for applications requiring 100% sealing of flue gas and process gases.
Our sealed air design operates by continuously maintaining a pressure higher than the upstream process pressure to preserve the seal clearance of the damper blades. Our flexible special-alloy seals retain durability even at high temperatures, making them well suited for heavy-duty applications.
Butterfly, multi-louver, guillotine and diverter dampers can all be equipped with sealed air systems to achieve 100% tight shut-off.
FORENSERVTEK can design and supply complete sealed air systems, including air ducts, heaters, return air units, fans and mounting accessories. We evaluate the specific process data of your project to calculate and determine the optimum fan size, power consumption and sealed air control strategy for your requirements. Fans and control units can be supplied with relevant certifications for use in hazardous areas, such as ATEX.
