How does a refrigeration solenoid valve work?

A refrigeration solenoid valve operates as an electrically controlled device that regulates the flow of refrigerant in a cooling system. When an electric current is applied to the solenoid coil, it generates a magnetic field that moves a plunger, opening or closing the valve. This action allows or restricts the flow of refrigerant based on the system's demands, thereby contributing to the efficient operation of the refrigeration cycle. The valve can be used for various functions, such as controlling the flow in liquid and suction lines.
