The LDI ED12 Electronic Drain Valve (115V, 50/60Hz) is a direct replacement or upgrade for Atlas Copco part number 23441686797. Designed for operating pressures from 0.2 to 16 bar, this zero-loss drain automatically removes condensate without wasting compressed air, improving system efficiency and reducing energy costs.
Key Features
-
Smart Electronic Control – Timer or level-sensing operation prevents air loss while ensuring reliable condensate discharge.
-
Wide Pressure Range – Works seamlessly from 0.2 bar to 16 bar (3–232 psi), suitable for low-pressure blowers to high-pressure compressors.
-
Global Voltage Compatibility – Operates on 115V AC, 50/60Hz – ideal for industrial applications in North America and other 115V regions.
-
Atlas Copco Compatible – Direct cross-reference to OEM part 23441686797; fits dryers, filters, receivers, and aftercoolers.
-
Robust Construction – Corrosion-resistant housing and high-cycle solenoid valve for long service life.
