Honeywell A-B720-S18 Valve Solenoid Coil

The Honeywell A-B720-S18 Valve Solenoid Coil is a replacement coil designed to energize compatible valves in industrial control systems. This unit features a black housing and 18-inch leads, enabling straightforward mounting and wiring in control panels or field wiring runs. As a solenoid coil, it converts electrical energy into a magnetic field that actuates the valve mechanism, producing the opening or closing action needed to regulate fluid or gas flow in automation processes. The model designation A-B720-S18 helps identify the coil for appropriate valve assemblies and spares, supporting interchangeability within compatible systems. With 18-inch leads, wiring flexibility is enhanced, allowing routing and connection to standard control circuitry without excessive strain on terminations. For reliable operation, technicians typically verify that electrical ratings and mechanical fit match the existing valve hardware when replacing a coil. The observable features—black housing and 18-inch leads—assist buyers in confirming this part as a direct replacement for compatible A-B720-S18 valve assemblies in industrial automation environments.
