Two-Stage Jet Pipe and Three-Stage Nozzle Baffle Servo Valve

The two‑stage jet pipe servo valve adopts jet pipe as pilot stage with better contamination resistance than conventional nozzle‑flapper design. The three‑stage nozzle‑flapper servo valve adds an extra power‑amplification stage based on two‑stage structure to deliver high flow. Both realize electro‑hydraulic conversion via hydraulic pilot amplification and closed‑loop feedback for precise control of cylinder position, velocity and force.

Applications: High‑flow test rigs, motion simulators, aerospace hydraulics and other high‑power precision closed‑loop systems.
