Abstract
A solenoid operated valve assembly is provided. The valve assembly may include a solenoid having a solenoid coil and an armature movable under influence of the solenoid coil. The valve assembly may also include a valve member operably connected to the armature and configured to selectively contact a valve seat. The valve assembly may further include an outer body containing the solenoid, the armature, the valve member, and the valve seat. In addition, the valve assembly may include a grounding device including an electrically conductive element disposed between the valve member and the outer body.
