2) Operation
If the power supply is connected to the water inlet valve, the rod valve is drawn by the coil's magnetic field to
open the diaphragm hall and push up the diaphragm with water pressure. This leads to open the water flow and
start the water supply. If the power supply is cut off, the coil's magnetic field disappears and the force of internal
spring leads the rod valve to close the diaphragm hall, leading to block the water flow.
