A proximity sensor valve includes a housing which defines a fluid inlet and a fluid outlet in communication with a cavity. A plunger pin within the cavity for movement along an axis, the plunger pin movable between an extended position and a retracted position. The plunger pin extends at least partially outward of said housing at the fully extended position. A spool is within the cavity for movement along the same axis as the plunger pin, such that the spool and the plunger pin are movable with respect to each other to control fluid flow between the fluid inlet and the fluid outlet.
