What is 2-Stage Servo Valve Design and Operation about?

The document describes the design and operation of a 2-stage servo valve with mechanical feedback. It has a first stage torque motor that moves an armature which is connected to a flapper. The flapper sits between two nozzles and controls fluid flow. This creates a pressure differential that moves the second stage spool. The spool controls flow to actuator ports. A feedback wire connects the flapper to the spool to hold it in position proportional to electrical current. When current is removed, springs retu
