Slide Gate Damper S500

Slide Gate Damper for Demanding Industrial Processes

The Swedamper S500 Slide Gate Damper is a robust industrial damper providing 100% geometric tightness and unrestricted flow in the open position. The damper blade retracts completely from the duct, allowing unobstructed flow with no pressure drop caused by the blade.

The S500 is suitable for flue gases, high dust loads, and abrasive bulk materials in industries such as pulp and paper and heavy process industries, including raw mills for ore and limestone. The damper can be customized with different materials, sealing options, and configurations to meet specific process requirements.

Description

Slide Gate Damper S500 – for Demanding Industrial Flow Applications

The Slide Gate Damper S500 is a robust industrial damper designed for flow control and shut-off in ducts and chimneys. Its design provides 100% geometric tightness in the closed position, while the damper blade is fully retracted from the duct when open. This provides an unrestricted flow path without pressure drop caused by the damper blade.

The S500 is suitable for both flue gases and bulk materials and is developed for demanding process environments involving high dust loads and abrasive materials. Typical applications include the pulp and paper industry as well as heavy process industries, for example raw mills handling ore, limestone, and similar materials.


100% Geometric Tightness and Unrestricted Flow

A key feature of the S500 is the combination of 100% geometric tightness and a completely unrestricted flow path when the damper is open. When opened, the blade is fully retracted from the duct, ensuring that it does not remain in the flow path or cause any additional pressure drop.

This is particularly beneficial in processes where large volumes of flue gas, dust, or bulk materials pass through the system and where both reliable shut-off and unrestricted flow in the open position are essential.

The design makes the S500 well suited for environments with high dust loads and abrasive materials, including applications in the pulp and paper industry. It can also be used in heavier industrial processes, including raw mills for ore, limestone, and similar materials.

The product documentation also confirms that the blade is fully retracted from the duct for unrestricted flow and that materials can be selected to withstand abrasive conditions.


Robust Design for Round and Square Ducts

The S500 features a robust and stable construction with a high degree of flexibility for different installations. The damper can be integrated into both round and square ducts, making it suitable for a wide range of industrial process systems.

Multiple layers of seals are used to prevent leakage to the atmosphere. The housing can also be enclosed and equipped with a cast stuffing box to prevent smaller particles from escaping.


Damper Blade Operation

The damper blade can be operated by a pneumatic cylinder in a fixed rising-stem configuration or by a gear drive in a rotary non-rising configuration. This allows the actuation system to be adapted to the specific installation and process requirements.


Flexible Material and Sealing Options

Materials for the housing, damper blade, and flanges are selected according to the application. Factors such as temperature, corrosive environment, and abrasion determine the most suitable materials. Different materials can also be combined, for example by using different alloys for the housing and damper blade.

Blade seals are available in materials including PTFE, fiberglass, and steel. Flanges can be manufactured according to customer specifications, Swedamper standards, or other recognized industry standards. The S500 can also be manufactured in a wide range of alloys to meet specific process requirements.

The datasheet lists additional sealing materials, including NBR, EPDM, Viton, silicone, PTFE, butyl, E-glass, and ceramic fiber/Inconel. Each material offers different properties and temperature capabilities and is therefore selected according to the specific process conditions.


For High Temperatures and Demanding Process Environments

The S500 can be adapted for high-temperature processes. The product range includes S500-HT (High Temperature) for high-temperature applications and S500-R (Refractory Lined) with an internal refractory lining for extreme temperatures.

The product documentation specifies operating temperatures of up to approximately 1100°C, depending on configuration and material selection, and sizes ranging from DN250 to DN3000.

The datasheet material table specifies the maximum temperature for each construction material, including carbon steel, Cor-Ten A, 16Mo3, stainless steel, acid-resistant stainless steel, Alloy 800HT, 253MA, and 254SMO.


Applications and Typical Installations

The Slide Gate Damper S500 is designed for industrial systems where flow through a duct or chimney needs to be controlled or shut off. Typical applications include:

  • Combustion furnaces
  • District heating plants
  • Smelters
  • Flue gas systems
  • Process ducts and chimneys
  • Bulk material handling
  • Processes requiring unrestricted flow in the fully open position

Customization and Special Configurations

The S500 can be engineered to meet the specific requirements of each installation. Materials for the housing, blade, and flanges can be selected and combined according to factors such as temperature, corrosion, and abrasion.

Flanges can be manufactured according to customer requirements, and the datasheet includes flange dimensions for materials such as S235, stainless steel EN 1.4301, and acid-resistant stainless steel EN 1.4404.


Summary

The Swedamper Slide Gate Damper S500 is a flexible and robust industrial damper for controlling and shutting off flue gases and bulk material flows in demanding process environments. Its fully retractable blade provides an unrestricted flow path when open, while multiple sealing options and customizable materials provide flexibility for different operating conditions.

With sizes ranging from DN250 to DN3000, high-temperature configurations, and customizable materials, seals, flanges, and actuation systems, the S500 can be engineered to meet the specific requirements of the process and installation.
