Butterfly Dampers

We understand the intricate needs of industrial and commercial applications. That’s why we specialize in providing top-tier butterfly dampers, tailored to meet your specific requirements.

Flexibility is key. We provide butterfly dampers that can be actuated pneumatically, electrically, or manually via a simple hand lever or reduction gearbox. This ensures that you have the control you need, exactly how you need it.

What are butterfly dampers?

Butterfly dampers are essential components designed to control and isolate gas flows in various systems. Whether it’s exhaust systems, air ducting, or tunnel ventilation, our butterfly dampers offer precise control and robust isolation, ensuring efficiency and safety in your operations.

What are they made of?

They are manufactured in fiberglass or stainless steel, and for special applications, we offer materials like 800HT, 310S, Alloy 31, Alloy 59, and more. These materials are selected to withstand the demanding conditions of your industry, providing long-lasting performance.

Methods of Actuation:

Flexibility is key. We provide dampers that can be actuated pneumatically, electrically, or manually via a simple hand lever or reduction gearbox. This ensures that you have the control you need, exactly how you need it.

What is Manual Actuation

Manual actuation involves manually operating the damper by turning a handle or lever. Manual actuation is simple and affordable but may be challenging for larger or hard-to-reach dampers.

What is Pneumatic Actuation

Pneumatic actuation uses compressed air to operate the damper via a pneumatic actuator. Pneumatic actuation is relatively quick, precise, and suitable for many industrial applications. However, it requires an air supply and may be vulnerable to leaks.

What is Electric Actuation

Electric actuation uses an electric motor to operate the damper via an electric actuator. Electric actuation is precise, efficient, and ideal for automation and precise control. However, it can be costly and requires an electrical supply.

What is Hydraulic Actuation

Hydraulic actuation uses hydraulic fluid to operate the damper via a hydraulic actuator. Hydraulic actuation provides high force and is ideal for large dampers or those requiring precise control. However, it can be costly, require maintenance, and may be prone to leaks.

Optional Extras for Custom Solutions

Butterfly dampers come with a range of optional extras, ensuring that you get the perfect match for your application.

Pneumatic Cabinet

Enhance your control with our pneumatic cabinets, designed to offer precise actuation. These cabinets are engineered to work seamlessly with our products, providing you with reliable and efficient operation.

Maintenance-Free Bearings

Benefits and Considerations

Compact Design and Economy: Engineered with a space-saving compact design that fits seamlessly into your existing systems.

Shutoff Rates and Temperature Consistency: With shutoff rates of up to 99% and a design that remains consistent across temperature swings, our butterfly dampers offer unparalleled reliability. Whether it’s controlling gas flows in exhaust systems or maintaining stability in tunnel ventilation, our products provide the control and consistency you need for optimal performance.

Actuators can be fitted with a manual override in case of a loss of power or air pressure.

Shaft Usage and Types of Seals: The shaft in our butterfly dampers is designed to operate smoothly, intersecting the linkage, bearing, packing, and blade in perfect harmony.

Additionally, we offer a variety of seals, including tadpole seals for better compression and metal seats for specific needs, ensuring a perfect fit for your application.
