Construction details of Butterfly Damper:
- Frame: Mild Body steel conforms to IS2062, and boiler grade steel conforms to IS2002 with continous welded flanges. Structural channel is available for larger size dampers.
- Vanes: A single thick plate is offset and formed at the shaft to provide additional strength, with reinforcing ribs added as needed for the intended service. The vane is welded to a continuous through-shaft made from stainless steel or other corrosion- and abrasion-resistant materials.
- Shafts: The shaft ends are marked to show the vane position, and the shafts are made of stainless steel, available as continuous or stub types.
- Bearings: Ball or bush bearings are mounted outboard on stand-offs, positioned above adjustable packing glands.
- Gland: The unit features an adjustable plate and follower design. It is sealed with standard fiberglass rope packing, with options for ceramic rope or other commercially available packing materials to suit specific application requirements.
- Seals: No internal vane seals are provided. Instead, a tight swing clearance between the vanes and the frame is engineered to achieve approximately 98% shut-off when the damper is in the fully closed position.
- Paint: The damper undergoes hand cleaning and receives one shop-applied coat of a standard industrial primer. Custom painting is available and will be applied according to the customer’s specifications.
- Operator: An extended operator shaft is provided as standard for operating it with actuators. A comprehensive range of manual, electric, and pneumatic operators is available. These can be configured with options for modulating control, fail-safe operation, and position switches, and will be assembled based on the customer’s specific requirements.
Industrial Applications of Butterfly Dampers:
Steel Plants: Applications in hot-air systems, furnace exhaust, gas ducting, cooling and process ventilation.
Cement Plants: Kiln exhaust, process gases, dust handling and high-temperature ducting.
Power Plants: Flue gas, combustion air, exhaust systems and heat recovery.
HVAC: Air balancing, ventilation, exhaust and large duct isolation.
Chemical & Petrochemical: Process gas handling and corrosive/temperature-sensitive applications.
Wastewater Treatment: Odour-control air systems, ventilation and process-air handling.
Pharmaceutical Plants: Controlled ventilation and process exhaust applications where suitable.
Pollution-Control Systems: Air and flue-gas isolation around scrubbers, filters and exhaust systems.
Butterfly Damper Price in India
The price of a butterfly damper depends on damper size, pressure, temperature, body and disc material, leakage requirement, sealing arrangement, end connection and actuation type.
Manual butterfly dampers are generally less costly than pneumatic or electrically actuated configurations, while high-temperature, special-alloy and low- or zero-leakage designs require application-specific engineering.
Butterfly damper manufacturers in India, such as Hubluxe Engineering, typically evaluate these operating and design requirements before preparing a project-specific quotation. To get an accurate butterfly damper price, send us your required size, operating temperature, pressure, medium, material and actuator preference. The Hubluxe Engineering team will recommend a suitable configuration and provide a project-specific quote.

FAQs (Frequently asked questions)

A butterfly damper is a flow-control and isolation valve used primarily in air, gas and flue-gas ducting and process systems. It uses a rotating disc or vane to regulate or isolate the flow.
The main difference between a valve & damper is that valve is installed in a pipeline to control or regulate the fluid flow while a damper is installed inside a duct, chimney, VAX box, air handler or any air handling equipment that regulates the flow of air or gases.
It act as cut off point in those areas where flow of air/gases are not required.
A well-designed butterfly damper HVAC system is used in air handling units, main duct lines, exhaust ducts, and ventilation zones to control, regulate, or isolate airflow.
It is ideal for applications that require efficient air distribution and effective flow management.
A butterfly damper works by using a circular disc (or blade) mounted on a central shaft to regulate or isolate airflow inside a duct. By rotating this disc, the damper increases or decreases the space available for air to pass through, effectively controlling the volume and pressure of gas in a system.
The operation is driven by an actuator (manual, pneumatic, or electric) attached to the external shaft. When the actuator turns, it rotates the internal disc anywhere from 0° (fully closed) to 90° (fully open). This rotational movement allows for precise flow modulation, enabling operators to maintain specific process conditions or shut off the flow entirely for maintenance.
Unlike standard valves, industrial dampers must handle high-volume, low-pressure applications, often involving high temperatures or dust load. To ensure efficiency, Hubluxe Engineering designs the sealing contact between the disc and the body to minimize leakage (tight shut-off). This construction ensures durable performance in HVAC and industrial exhaust systems, complying with ISO 9001:2015 quality management system for safety and longevity.
