The automatic drain valve is a valve installed at a low point in the compressed air system (such as the bottom of the gas tank, the evaporator of the cold dryer, the filter, etc.) to automatically and regularly discharge accumulated condensed water, oil and other liquids without manual operation.


Features and Advantages 

 ◦ Fully Automatic Operation: 

Eliminates the need for manual, timed wastewater drainage, saving labor costs and preventing equipment damage caused by neglect.

◦ Prevents Liquid Accumulation: 

Promptly drains harmful liquids, protecting the air tank from corrosion and preventing condensate from re-entering the compressed air pipeline.

◦ Ensures Equipment Efficiency: 

For dryers and filters, timely drainage is critical to their efficiency and lifespan.

◦ Diverse Operating Modes: 

Commonly used are float-type (mechanical, automatically activates when the liquid level reaches a certain level) and electronic timer (activates at set intervals, offering greater intelligence and energy savings).


Application Industries

Any compressed air system equipped with air tanks, dryers, and filters requires this installation. It is a key component for ensuring automated system operation and maintenance.
