Solenoid valves are electromechanical devices controlling fluid flow via electromagnetic force. They consist of a coil, plunger, and valve body. When energized, the coil generates a magnetic field, moving the plunger to open/close the valve; de-energization resets it. Available in 2-way, 3-way, 4-way types, they handle liquids, gases, or steam. With fast response, precise control, and low power use, they’re vital in plumbing, HVAC, automotive, medical, and industrial automation, ensuring efficient fluid regulation in diverse systems.
