Atlas Copco EWD Electronic Drain Valve Inquiry Item

This Atlas Copco EWD series electronic drain valve is specially used for compressed air system to automatically discharge condensed water. It adopts capacitance liquid level detection principle, automatically opens and closes according to the liquid level of condensate, avoiding continuous air loss caused by timing drainage. It is equipped with power, valve and alarm indicator lights, and comes with a manual test button for on-site function inspection. Built-in fault self-diagnosis function, it can send alarm signal when the drain is blocked or faulty. The metal valve body has good pressure resistance and corrosion resistance. Common models include EWD50, EWD75, EWD330 and EWD1500, which are widely matched with Atlas Copco air compressors and freeze dryers.
