The auto drain valve is a crucial component used in compressed air systems to automatically remove accumulated condensate, water, and oil particles without interrupting the air flow. It helps maintain the efficiency and longevity of compressors by preventing moisture build-up that can lead to corrosion, contamination, and system damage. Ideal for use at the compressor outlet or before the dryer, the auto drain valve ensures clean, dry air and reduces the need for manual draining, making the system more reliable and maintenance-friendly.

A Sensor-Based Auto Drain Valve is a device installed in compressed air systems,
steam systems, or industrial pipelines to automatically remove accumulated condensate (water, oil, or other liquids) without manual intervention.
The valve uses a sensor to detect the presence of condensate and triggers the valve to open and discharge the fluid,
preventing system damage, corrosion, or performance loss.
The working of the sensor-based auto drain valve is as follows:
Advantages: Prevents system damage, reduces energy loss, and allows continuous operation without manual intervention.
