We describe a new two-stage aerospace servovalve which has an additively manufactured titanium body, and a small piezoelectrically actuated spool as its first stage, with electrical main stage position feedback. The approach promises to provide low weight, low leakage, and more accurate spool positioning. In addition, it enables increased manufacturing automation thereby reducing cost, increasing repeatability, and generates less waste material. Valve design, operation and measured performance are discussed in this paper.
