Wear-resistant electro-pneumatic converters

Wear-resistant electro-pneumatic converters are disclosed. An electro-pneumatic converter includes a body including an axial passageway extending between a first opening and a second opening, the first opening associated with a supply port, the supply port to receive pressurized fluid from a pressure supply source, a solenoid disposed within the axial passageway, an armature including a first side and a second side opposite the first side, the second side facing the solenoid, the armature movable between a first position and a second position, the pressurized fluid blocked from flowing through the output port when the armature is in the first position, the pressurized fluid to flow through the output port when the armature is in the second position, and a spring coupled to the first side of the armature, the spring to bias the armature toward the first position.
