At rest, it can be normally open (NO) or normally closed (NC). A solenoid has an electromagnetically inductive coil (A) around an iron core at the center called the plunger (E).
Wide range of applications: Versatile for various industries, including water treatment, automotive, and food processing.įigure 2: Components of a solenoid valve coil (A) armature (B) shading ring (C) spring (D) plunger (E) seal (F) valve body (G)Ī solenoid valve consists of two main components: a solenoid and a valve body (G).
This is the basic principle that is used to open and close solenoid valves. The magnetic field exerts an upwards force on the plunger opening the orifice. An electric current through the coil creates a magnetic field. In the rest position, the plunger closes off a small orifice. The valve features a solenoid, which is an electric coil with a movable ferromagnetic core (plunger) in its center. A solenoid valve is an electrically controlled valve.
