The Solenoid Water / Air Valve 12 V DC is an electrically operated valve used to control the flow of water, air, or other non-corrosive fluids automatically. When energized with 12 V DC, the valve opens or closes instantly, enabling precise flow control in automation systems. It is widely used in RO systems, smart irrigation, air control, and embedded automation projects due to its fast response and reliable operation.
