Buy Louver Damper Valve DBD-1 0.005MPa Stainless Steel Flanged Electric Actuated
The DBD-1 Electric Louver Damper Valve by VALVEHU is designed to deliver precise airflow regulation in large-diameter, low-pressure industrial duct systems. Built for control applications in metallurgy, building materials, chemical processing, power stations, and environmental engineering, this damper is highly suitable for dusty air, flue gases, and cold or hot ventilation pipelines.
Equipped with a robust electric actuator, the DBD-1 model allows for smooth modulation or shut-off of airflow. Its louvered blade design enhances aerodynamic efficiency, making it ideal for high-volume, low differential pressure systems. The valve structure integrates multiple air passages and efficient sealing, providing leak rates under 3% and full closing within approximately 25 seconds.
With a nominal pressure rating of 0.005 MPa and operating temperature range from -30°C to 350°C, this electric damper performs reliably in diverse industrial conditions. It supports input signals such as 4–20mA or 0–10mA, and standard electrical supply is 220V ±20V at 50Hz. The low-resistance stainless steel or galvanized body offers long service life and corrosion protection.
Connection is achieved through flanged ends, ensuring compatibility with standard pipeline setups. Sizes are available from DN500 to DN1600, accommodating larger ductwork applications. The modular build also allows integration with various actuator types for custom control needs.
Whether you require automated regulation of gas or dust-laden air, the DBD-1 series damper valve provides reliability, precision, and low maintenance.
