Project Description


Bi-stable solenoid valve is also named latching solenoid valve. It includes a set of permanent magnets that allow the solenoid to offer hold force even after the power is off. The term Bi-stable is given to this type of solenoid because it has two stable positions.

The first when the solenoid de-energized and plunger is fully extended and second when the solenoid is de-energized and the plunger is held in position by the permanent magnets.


  • No self heating.
  • Continues to hold even after the power is disconnected.
  • Can operate by a pulse signal.
  • A charge / discharge of capacitor will be enough to set and reset.
  • 2 way normally closed.
  • Max. Burst pressure: 12 Bar.
  •  Working pressure: NC 0.2-8 bar.
  • Medium: Air, water, hot water, light oil, diesel.
  • Valve body: brass
