ABSTRACT:
A solenoid valve is disclosed including a valve housing having a central bore and a valve seat, a valve element movable between an open position allowing fluid to pass through said valve seat and a closed position in sealing engagement with said valve seat, a valve operator for moving the valve element between the open and closed positions including a reciprocating armature plunger member extending through the bore and an armature secured to the armature plunger, a valve adjustment for adjustably mounting the valve element relative to the valve operator for permitting adjustment to within an acceptable tolerance of a predetermined distance between the valve element and the valve seat when the valve element is in its open position without creating a path of leakage when the valve element is in its closed position. A valve adjustment securing mechanism is provided for securing the armature to an armature end of the armature plunger and a load bearing insert is secured within the armature for bearing a load exerted by the armature plunger during reciprocation of the valve element to allow for surface contact during the valve operation without surface wear.
