12V Plastic Bistable Latching Solenoid Valve With Normally Open Normally Closed Function
working principle
Dual pilot solenoid pilot valve structure having a mechanical self-locking memory function self-holding type. When the coil member "B" is energized, the solenoid valve is opened, then off, then the solenoid valve is a normally-on state, when the component coil "A" is energized, the solenoid valve is closed, then power off, when the solenoid valve is normally closed. If the coil "A", "B" is energized at the same time, when the solenoid valve is a normally-on state, the coil will not result in burnout. This valve can be applied to the next switching cycle longer than the work environment.
