     Solenoid Valve Oil & Gas
     A solenoidrnvalve is an electro-mechanical controlled valve. The valve
    features a solenoid,rnwhich is an electric coil with a movable ferromagnetic
    core in its center. Thisrncore is called the plunger. In rest position, the
    plunger closes off a smallrnorifice. An electric current through the coil
    creates a magnetic field. Thernmagnetic field exerts a force on the plunger.
    As a result, the plunger isrnpulled toward the center of the coil so that
    the orifice opens.
