Water solenoid valves are specifically designed for liquid flow control using electromagnetic principles. These valves are widely used in systems like automatic irrigation, tap water supply, air conditioning, and industrial production. Their main function is to regulate, cut off, or permit the flow of water or other liquids with precision and efficiency.

2. Working Principle

The water solenoid valve contains a sealed chamber with openings connected to various pipelines. Inside the chamber, a valve core moves based on the activation of electromagnetic coils. By energizing the appropriate coil, the valve core shifts to block or release specific flow paths, controlling the flow direction and pressure. This movement translates into precise control of mechanical devices connected downstream.

The pilot solenoid valve is suitable for applications with pressure differences between the front and rear of the valve, particularly for large diameters.
The pilot solenoid valve operates as follows: When energized, electromagnetic force lifts the valve stem, opening the pilot port. This relieves pressure in the upper chamber through the pilot hole, creating a high-low pressure difference around the main valve core. Under this pressure, the fluid pushes the main valve core upward to open the main valve port. When de-energized, the valve stem resets under spring force and the weight of the main valve core, increasing pressure in the upper chamber. The fluid pressure then pushes the main valve core downward, closing the main valve port.
