Latching solenoid valve
A latching solenoid valve can retain a switched state after an electrical command without the same continuous energization as a conventional coil, although retention methods vary. Polarity, pulse, reference state, and reset are not defined by the name. Circuit design must take power-loss behaviour, command energy, feedback, and manual or electrical reset from the actual datasheet.
Application and duty
Low-energy switching or state retention with documented command and reset logic
