Three-Stage Electrohydraulic Flow Controlling Servo Valve with Two Nozzles and Flapper Force Feedback

Design Features
(1) Using a double-nozzle flapper valve as the pilot stage, and furnished with electric feedback for main valve core position.
(2) Good dynamic behavior, and low energy consumption. Able to meet requirements for valves with high frequency response and flow from industrial fields.
(3) Using an external controlling amplifier for easy adjustment, and allowing a user selecting external controlling and discharging way for pilot controlling oil.
