A solenoid valve is an electromechanical device that controls the flow of fluids (in this case, hot water) within a system. It uses an electric current to generate a magnetic field, which opens or closes a valve. The valve itself is typically composed of a coil, plunger, and a spring. When an electrical current passes through the coil, the magnetic field either pulls or releases the plunger, allowing hot water to flow or stop flowing depending on the configuration of the valve.

    In the case of a Hot Water Solenoid Valve, the device is specifically designed to handle high temperatures, ensuring the efficient and safe flow of hot water. These valves are typically made from materials that are resistant to heat and corrosion, such as brass, stainless steel, or durable plastic compounds.
