Principle of three-way solenoid valve

Working principle of three-way solenoid valve: one inlet and two outlets: (ZC2/31) When the solenoid valve coil is energized, the first outlet (2) is open and the second outlet (3) is closed;
When the solenoid valve coil is de-energized, the first outlet (2) is closed and the second outlet (3) is open; two inlet and one outlet: (ZC2/32) When the solenoid valve coil is energized, the first outlet (2) is open and the second outlet (3) is closed; when the solenoid valve coil is de-energized, the first outlet (2) is closed and the second outlet (3) is open; (a one-way valve must be added before the two inlet ends of this internal valve), one inlet and one outlet: normally closed (ZC2/3)—when the solenoid valve coil is energized, interface 2 leads to interface 1 and interface 3 is closed;
When the solenoid valve coil is de-energized, interface 2 is closed and interface 1 leads to interface 3; Normally open (ZC2/3K)—When the solenoid valve coil is powered off, interface 3 leads to interface 1 and interface 2 is closed; when the solenoid valve coil is powered on, interface 3 is closed and interface 1 leads to interface 2.
