Jaloussie Valve

Jalousie dampers are durable and reliable flow control components used for directing, regulating, and shutting off air, gas, and dust-laden fluids. They are widely utilized in power plants, cement factories, mining, chemical plants, metal processing, and ventilation systems. These dampers ensure high efficiency and seamless operation, even in abrasive and high-temperature environments.

Jalousie dampers are particularly used in airflow or gas transport systems with large duct cross-sections, allowing precise airflow adjustment while minimizing energy losses. With manual or automated operation, they offer flexible usage options for industrial facilities.

How Do Jalousie Dampers Work?

• Flow is enabled: The blades open, allowing air or gas to move freely.
• Flow is blocked: The blades close, completely stopping air or gas movement.
• Adjustable flow control: The blades can be positioned at specific angles to regulate flow rate.

These features help optimize airflow or gas movement, enhancing energy efficiency and workplace safety.

Advantages of Jalousie Dampers

• Precise flow control: The opening angle can be adjusted to regulate airflow or gas passage.
• Low pressure loss: Special design minimizes resistance in fluid movement.
• Durable and long-lasting construction: Made from stainless steel, carbon steel, or specially coated materials, ensuring resistance to abrasive and extreme environments.
• High temperature and pressure resistance: Performs exceptionally well in industrial furnaces, cement plants, and metal processing facilities.
• Manual or automated operation: Can be controlled manually, pneumatically, or with an electric motor.
• Suitable for dusty environments: Optimized for air ducts, exhaust gas systems, and filtration plants.

Applications of Jalousie Dampers

• Cement & mining: Used in kiln gas control, exhaust gas redirection, and dust collection systems.
• Power plants: Regulates hot gas and air flow in electrical power facilities.
• Metal processing & foundries: Controls high-temperature gas movements.
• Chemical & petrochemical: Manages gas flow during chemical reactions.
• Ventilation & filtration systems: Adjusts airflow in large-scale ducting, improving energy efficiency.
• Waste management & exhaust gas treatment: Used for emission control and gas filtration.

Types of Jalousie Dampers

• Manual Jalousie Damper: Hand-operated, providing a simple and cost-effective solution.
• Pneumatic Jalousie Damper: Uses air pressure for fast opening and closing operations.
• Electric Jalousie Damper: Integrates with automation systems, enabling precise air/gas control.
• Double-layer Jalousie Damper: Withstands higher temperatures and pressures, commonly used in industrial furnaces.
• Stainless Steel Jalousie Damper: Corrosion-resistant, making it ideal for chemical and food industries.

Key Considerations When Choosing a Jalousie Damper

• Type of fluid: The system must be suitable for air, exhaust gases, hot gases, or chemical vapors.
• Pressure & temperature resistance: Materials should withstand high temperatures and pressures.
• Automation requirements: The system should be selected based on manual, pneumatic, or electric control needs.
• Connection type: Flanged or in-duct mounting options should align with facility infrastructure.
• Sealing efficiency: High-quality sealing materials should be used to prevent air leakage.
