Precise Airflow Control for Your Duct System
The air volume regulating valve is a simple yet essential device used in ventilation and air conditioning ducts. Its main function is to adjust the air volume in branch ducts or to mix fresh air and return air. This product is available in manual and electric types. The electric version can be connected to your building's automatic control system. With its reliable design, this air volume regulating valve helps you achieve precise airflow for comfort and efficiency.
Built for Durability and Smooth Operation
Our product features mature and reliable craftsmanship. The blades use an opposed-blade design, allowing precise adjustment at any angle. They resist deformation even after long-term use.
The frame is robust: the top plates are bent at 90° to wrap around the side panels and are secured with rivets. The corners use 90° corner brackets for a rigid structure. The linkage mechanism uses thicker flat steel bars for greater strength, preventing bending during transmission. A brass bushing inside the valve seat protects the shaft and blades from wear, greatly extending the service life of the air volume regulating valve.
Key Performance Specifications and Materials
Understanding the performance characteristics of an product helps you make the right choice.
The relationship between blade opening and airflow is not perfectly linear. Lower resistance when fully open is preferable. The leakage rate indicates sealing performance-the lower the leakage rate, the better the sealing. Adjustment accuracy depends on the transmission mechanism.
