Air damper valve is a mechanical device that controls air volume in a duct used to control the flow of air in an HVAC (heating, ventilation, and air conditioning) system. Air damping valves are divided into manual damping valves, electric damping valves and check valves, and different control types are suitable for different working environments. The materials used to make air dampers can vary depending on the specific application and environmental factors.

Common air duct damper valve materials:

Stainless steel damper valve

Stainless steel is a commonly used material in air damper valves because it is durable and resistant to high temperatures, but the manufacturing process is complicated and the manufacturing cost is high. It is usually used in high-end office buildings and high-temperature and high-pressure ventilation systems.

Aluminum air damper

Aluminum is another popular material used in air dampers because it is lightweight, corrosion-resistant, easy to machine and inexpensive to manufacture. However, the aluminum air damper valve has poor anti-corrosion performance and is easy to corrode in a high acid-base environment, so it is not suitable for corrosive gases.

Plastic Air Damper Valve

Some air valves are made of plastic, such as PVC or PP, because it is lightweight, cheap, and corrosion-resistant, and PP air valves can be injection molded into regular sizes with good sealing performance, and larger sizes can be processed and customized. Due to the low production cost, it has high cost performance. However, the plastic material is not resistant to high temperature and cannot be used in a high temperature environment.

The advantages of using air damper valves in HVAC systems include:

1. Improved Energy Efficiency: Air damper valves help regulate airflow in HVAC systems, increasing energy efficiency and reducing energy costs,.

2. Improved Air Quality: By controlling airflow with a combination of temperature and humidity sensors, air damping valves help maintain optimal air quality in a building or space.

3. Increased comfort: Air damper valves help distribute air evenly throughout the space, increasing comfort and reducing hot or cold spots.

4. Noise Reduction: Air damper valves help reduce noise in HVAC systems by regulating airflow and minimizing turbulence.

   
   

In short, the damper valve is an important part of the HVAC system, and its manufacturing materials can be selected according to specific application requirements. Before purchasing an air damping valve, it is recommended to communicate and negotiate with technicians or damper valve suppliers to determine the material, size, control type, etc. of the air damping valve.
