1. A valve, comprising:
a fluid inlet;
a fluid outlet;
a regulator coupled to the fluid inlet and having a regulator outlet;
a solenoid comprising an armature configured to retract a retraction distance from a closed position to an open position to allow fluid flow between the regulator outlet and the fluid outlet, the armature adapted to stop fluid flow between the regulator outlet and the fluid outlet in the closed position; and
a flow ring comprising at least one slot through which fluid flows between the regulator outlet and the fluid outlet in the open position, the flow ring configured such that an increase in the retraction distance exposes more of the at least one slot for fluid flow between the regulator outlet and the fluid outlet.
