Each damper will be calibrated before leaving the factory. Ensure the air volume is accurate

The internal valve core changes according to the change of the air inlet pressure on the left side of the pipe, and the right outlet air is constant;
The internal execution valve stem changes according to the change of the required air volume, and the right outlet air speed changes with the left side;
No matter how the pressure in the air duct system changes, the valve can automatically adjust the opening to ensure that the air volume is always within the set range.
Adopting a mechanical self-balancing structure, no electric drive or complex control system is required, making the operation more stable and reliable.
ABS material has good acid and alkali resistance and corrosion resistance, and is suitable for humid environments and clean room applications.
By accurately controlling the air volume, we can avoid energy waste caused by excessive air supply and improve the overall system operating efficiency.
Compact structure, light weight, can be quickly installed in the air supply or exhaust duct, and the subsequent maintenance cost is low.
Customized solutions can be provided according to customer air volume requirements, pipe diameter size and project requirements.
