The Top-Level Coil in a solenoid valve is the main coil responsible for generating the magnetic field that activates the valve mechanism. It is usually wound around a ferromagnetic core, which helps concentrate the magnetic flux. When an electric current is passed through the top-level coil, it creates a magnetic field. This magnetic field then attracts or repels a plunger or armature within the solenoid, depending on the valve design. The movement of the plunger or armature controls the opening or closing of the valve, allowing or blocking the flow of fluid or gas.Attributes:• Manufactured to a precise specification and are built for durability, reliability, and productivity.• Nominal System Voltage 12/24VDC• Current 1.6A at 150°CApplications: The Top-Level Coil typically refers to the primary coil or the main coil used to actuate the valve.
