ABSTRACT:
A solenoid valve system, wherein the valve member is provided with a seal member disposed thereabout. The solenoid valve is especially suitable for use with exhaust gas recirculation systems. The seal member is operable to slide axially relative to the valve member, including the stem portion thereof. An optional lubricant is provided between the valve member and the seal member so as to provide a relatively low friction environment therebetween when the valve member is in motion. An optional biasable member, in operable association with the seal member, is provided so as to maintain proper positioning of the seal member, e.g., during operation of the solenoid valve system.
