(EN)High-Efficiency Multi-Louver Damper Valve for Stable Airflow & Tight Shutoff
(ID) Katup Damper Louver Multi Efisiensi Tinggi untuk Aliran Udara Stabil & Penutupan Rapat
Introduction
A Louver Damper Valve—also known globally as Multi-Louver Damper, Industrial Louver Damper, Louver Isolation Damper, Airflow Control Louver, Duct Louver Damper, Parallel-Blade Damper, Opposed-Blade Damper—is a key component in large industrial ducting systems.
It provides precise airflow modulation, tight shutoff, and low-leakage control for industries such as cement, power generation, steel, metallurgy, petrochemical, and mining.
Designed for high temperature and high dust environments, Louver Dampers are widely used in:
- ID Fan / FD Fan ducts
- Rotary kiln and clinker cooler ducts
- SCR / FGD / ESP systems
- Hot gas ducts and bypass lines
- Industrial ventilation systems

What Is a Louver Damper Valve?
A Louver Damper Valve consists of multiple parallel or opposed blades, operating simultaneously to control gas volume.
Compared with butterfly dampers, louver systems offer:
- Better airflow distribution
- Lower pressure loss
- Higher sealing efficiency
- Lower operating torque on large ducts
- More stable modulation control
This makes it the preferred damper for medium to ultra-large duct sizes.
To better understand how damper systems work in industrial airflow control, you may refer to the engineering principles described here:

Key Features of LVRUI Louver Damper Valve
✔ Low-Leakage Sealing Design
Soft + hard sealing structures allow leakage levels of ≤2–3%, and with seal-air system, leakage can be reduced to ≤0.5%.
✔ High-Temperature Resistant
Material options include carbon steel, stainless steel (304/316), heat-resistant steel, suitable for 700–900°C.
✔ Airfoil Blade Shape
Reduces turbulence, improves airflow stability, and optimizes energy efficiency.
✔ Flexible Actuation Options
Electric, pneumatic, or hydraulic actuators with manual override.
✔ Compatible with DCS / PLC Systems
4–20 mA feedback, switches, Modbus, and other control options.
✔ Customizable Shapes & Sizes
Round, square, rectangular, or non-standard geometry available per project design.
Applications of Louver Damper Valve
Louver dampers are used in many industrial gas systems:
- Modulating control of fan airflow
- Isolation when combined with Guillotine Damper
- Bypass switching in SCR / FGD systems
- Kiln bypass and hot air furnace lines
- Clinker cooler exhaust regulation
Whether for airflow balancing or tight shutoff, Louver Dampers ensure reliability and high performance.
Industry engineers commonly follow standardized airflow and material-handling guidelines such as those published by:
