A solenoid valve is an electromechanically controlled valve that opens or closes in response to an electrical signal. When the solenoid coil is energized, it generates a magnetic field that pulls a plunger, allowing water to flow through the valve. When the current is turned off, the plunger returns to its original position, closing the valve and stopping the water flow. Specifically, cold water solenoid valves are designed to manage the flow of cold water, helping systems achieve precise water control with minimal effort.

    These valves are typically used in systems where automatic water regulation is necessary. For example, in washing machines, the cold water solenoid valve allows the appliance to fill with the appropriate amount of cold water when required, ensuring proper operation during the washing cycle.
