A proportional flow valve wherein a solenoid assembly moves an armature assembly towards a valve seat in proportion to the flow of current through the solenoid assembly. The armature assembly abuttingly engages a seal to hold the seal away from the valve seat at a distance correspondingly proportionally related to the applied current. In this manner, the seal is movable towards and away from the valve seat among a fully open position, a closed position, and partially open positions therebetween. A spring assembly biases the seal towards the valve seat and, when the solenoid assembly is energized, the armature assembly allows the spring assembly to seat the seal against the valve seat to place it in the closed position.
