What’s a micro air bleeding valve ?

Micro air bleeding valve is a kind of air inlet and exhaust device which can quicklyexhaust the air when the pipeline is filled with water,can quickly intake when thenegative pressure is generated in the pipeline,can discharge a small amount of gasgathered in the pipeline under normal working conditions,and can automaticallyclose the valve after the exhaust.

Functions of a Micro Air Bleeding Valve:

1. Exhaust function: The main function of the micro exhaust valve is to remove residual air or bubbles in the pneumatic system. During installation, operation, or maintenance, air pockets can accumulate in pneumatic systems, causing air lock, reduced efficiency, or erratic behavior of pneumatic components that can affect system performance.

2. Precise control: Micro exhaust valves are designed to precisely control the release of air or gas in the system. They often have small holes or openings that control the discharge of air without affecting the overall pressure or operation of the system.

3. Compact design: The micro exhaust valve has a compact, lightweight design, making it suitable for use in small spaces or applications with limited space. Their small size allows them to be easily integrated into pneumatic systems without significantly adding bulk or weight.

4. Maintenance: Miniature exhaust valves generally require minimal maintenance, and regular inspection and cleaning are sufficient to ensure proper operation. They are designed to withstand the rigors of continuous use and harsh operating environments without the need for frequent adjustments or replacements.
