Louver Damper Valve for Industrial Ventilation & Dust Control
（Katup Damper Louver untuk Ventilasi Industri & Pengendalian Debu）
High-efficiency multi-blade louver damper for precise airflow control, dust extraction, and industrial ducting systems
Overview
The Louver Damper Valve is a multi-blade industrial damper designed for precise airflow regulation, dust control, and pressure balancing in large ventilation ducts and material handling systems.
Compared with butterfly dampers, louver dampers provide larger flow area, smoother modulation, and better volume control, making them ideal for baghouse filtration systems, cyclone separators, pneumatic conveying networks, furnaces, boilers, silos, and industrial exhaust lines.
Its robust construction allows reliable operation under high dust load, high temperature, and continuous-duty industrial environments.

FAQS About Louver Damper Valves
What is a louver damper valve used for?
A louver damper valve is used to regulate, balance, or isolate airflow in industrial ventilation and dust control systems.
It is commonly installed in large duct lines, baghouse systems, cyclones, furnaces, and industrial exhaust systems, where precise airflow control and low pressure loss are required.
Compared with single-blade dampers, multi-louver designs provide smoother modulation and better airflow distribution.
Can louver damper valves be customized for different applications?
Yes. Louver damper valves can be fully customized based on duct size, operating temperature, pressure conditions, and material requirements.
Options include carbon steel or stainless steel construction, high-temperature design, and manual, electric, or pneumatic actuators, making them suitable for cement plants, power stations, and heavy-duty industrial environments.
What is the difference between a louver damper valve and a butterfly damper?
A louver damper valve uses multiple parallel blades to control airflow, offering smoother regulation and lower pressure loss in large ventilation systems.
A butterfly damper typically uses a single disc and is more suitable for simple on/off control rather than precise airflow balancing in large ducts.
For large-scale industrial ventilation and dust collection systems, louver dampers are usually preferred.
Where should a louver damper valve be installed in an industrial system?
A louver damper valve is typically installed in main ventilation ducts, branch ducts, or exhaust lines where airflow balancing or isolation is required.
It can be positioned upstream or downstream of bag filters, dust collectors, cyclones, furnaces, or air slide conveying systems, depending on system design and control requirements.
Proper installation ensures stable airflow distribution and improved dust control efficiency.
Is a louver damper valve suitable for high-temperature industrial applications?
Yes. Louver damper valves can be designed for high-temperature environments, especially in cement plants, kilns, boilers, and furnace exhaust systems.
By using heat-resistant materials, reinforced blade structures, and proper shaft sealing, the damper can maintain reliable operation under continuous high-temperature and dusty conditions.
