Pelajari fungsi katup butterfly damper dalam mengatur aliran udara pada sistem dust collector dan ducting industri, termasuk prinsip kerja dan keunggulannya.
What Is a Butterfly Damper Valve?
A Butterfly Damper Valve is a key airflow regulation device widely used in industrial ventilation and dust collection systems. It controls the volume of air or gas passing through pipelines by rotating a circular metal plate (butterfly disc) inside the duct or pipe.
This type of damper is commonly applied in:
- Cement plant dust collection systems
- Industrial ventilation ductwork
- Air conveying systems
- Boiler exhaust systems
- Material handling processing lines
Its compact structure and quick response make it a preferred solution for precise airflow management.
Working Principle of Butterfly Damper Valve
The working mechanism is simple and efficient:
√ The disc rotates around a central shaft √ 0° position allows full airflow √ 90° position completely blocks airflow √ Intermediate angles regulate flow volume
The valve can be operated using:
- Manual handwheel
- Electric actuator
- Pneumatic actuator
This flexibility ensures seamless integration into both automated and semi-automated industrial systems.
Structural Components
Main components include:
√ Valve body √ Butterfly disc √ Shaft √ Sealing ring √ Actuator system
The disc rotational movement enables accurate air volume control and ensures low pressure loss in the airflow path.
Advantages of Butterfly Damper Valve
√ Compact and space-saving design √ Fast response and easy operation √ Excellent air-tight sealing performance √ Low maintenance requirements √ Corrosion-resistant materials √ Suitable for high-temperature environments
These features make butterfly dampers ideal for harsh industrial conditions.
Typical Application Scenarios
√ Cement plant dust collection lines √ Clinker cooling system ducts √ Air slide conveyor ventilation √ Industrial drying systems √ Powder material pneumatic conveying
They play an essential role in stabilizing airflow and improving dust collection efficiency.
How to Select the Right Butterfly Damper Valve
When choosing a suitable model, consider:
√ Duct diameter √ Operating temperature √ Pressure conditions √ Control method (manual / electric / pneumatic) √ Media type (dust, air, gas)
Proper selection ensures optimal system efficiency and prolonged service life.
Why Choose Butterfly Damper Valves for Your Project?
Butterfly damper valves offer superior airflow regulation, reduced energy consumption, and enhanced dust control. They are widely adopted in cement plants, thermal power facilities, and bulk material processing sites where airflow stability is critical.
