An AC solenoid valve is a type of electromechanical valve that utilizes alternating current (AC) to operate. When electrical current flows through a coil, it generates a magnetic field that moves a plunger or armature within the valve. This movement either opens or closes a valve seat, allowing or preventing fluid from passing through. The operation can be either normally closed, which means it remains shut until electrified, or normally open, allowing flow until power is applied.

    Working Principle

    The working principle of an AC solenoid valve is rooted in electromagnetic fields. When power is supplied, the coil generates an electromagnetic field that pulls the plunger upward or downward. Depending on the valve's design, this movement will either seal the opening (in the case of normally closed valves) or release it (for normally open valves). The simplicity of the design allows for quick actuation, often within milliseconds, making AC solenoid valves suitable for applications that require rapid on/off control.
