ASCO 18AA Coil

ASCO 18AA Coil is a replacement solenoid coil for ASCO valves, rated for 115V AC at 60 Hz. It energizes the valve’s internal plunger to open or close the valve, enabling precise control of fluid or gas flow in industrial equipment. Designed to fit ASCO valve assemblies that specify the 18AA coil configuration, this coil reflects ASCO’s long-standing standard for coil form factors across multiple valve families. When replacing a coil, ensure compatibility with your specific valve model and series; cross-reference the coil code with ASCO’s catalogs or the valve’s label to confirm correct voltage, frequency, and termination type. Some ASCO coils use 18-inch lead wires, and suffixes like -D in ASCO part numbers denote this lead length in certain configurations, so check the exact ordering information for your application. Because voltage and frequency are specified as 115V at 60 Hz for this coil, it is compatible with standard North American power systems and equipment designed for 115/120V operation. For precise electrical characteristics, refer to the valve's datasheet or contact ASCO/Emerson support to verify the correct replacement coil for your valve series.
