The VCD damper regulating valve is a control device used to adjust the air volume in ventilation and air-conditioning projects. It is generally installed on the ventilation duct. Its main function is to control the air flow in the duct by adjusting the opening of the valve to meet different ventilation needs.

The volume control damper frame is usually produce by Volume Control Damper Frame Roll Forming Machine, which consist of decoiler, straightener, punch station, roll forming machine and bending machine.

Function of VCD damper

1. Air volume adjustment function

The VCD damper can adjust the air flow in the pipeline by adjusting the opening of the valve, thereby adjusting the air volume. In the ventilation and air conditioning system, the air volume is controlled to meet the requirements of temperature and humidity, ensure air quality, and achieve the purpose of energy conservation and emission reduction.

2. Noise reduction function

Installing an vcd air duct can prevent noise when air flows through the valve, thereby achieving the effect of noise reduction. This device needs to be installed in some places with noise requirements, such as hospitals, libraries, cinemas, etc.

3. Fire prevention function

The vcd air duct has a fire prevention function. In some buildings with high fire protection requirements, the use of this device can prevent the spread of fire, combustion and explosion in the pipeline.

4. Sound insulation function

In some noisy environments, installing an VCD damper can achieve sound insulation, thereby achieving a sound insulation effect.

Scope of application

It is widely used in HVAC systems of industrial and mining and civil buildings to precisely adjust the air flow. It is one of the key devices to achieve ventilation mode control in various environments. Its main features are flexible operation, low noise, small leakage (closed leakage < 0.5%), wide operating temperature range, reliable structure, safe and convenient
