A solenoid valve is an electrically controlled valve used to regulate the flow of water in various systems. In the case of a swimming pool, these valves are used to control the flow of water through different pool systems, such as the filtration system, heating system, or water features like fountains and waterfalls. The solenoid valve consists of a coil that, when energized, generates a magnetic field that opens or closes the valve. This allows or stops the flow of water depending on the system's needs.

    How Does It Work?

    The basic operation of a solenoid valve relies on electromagnetism. The valve body contains a plunger that is moved by an electromagnetic coil. When electricity flows through the coil, it generates a magnetic field that pulls the plunger away from the valve seat, allowing water to pass through. When the power is turned off, the magnetic field dissipates, and the plunger returns to its original position, closing the valve and stopping the water flow.
