Product Overview
The EMG SV 1-10/8/315/6 (Part No. 226694) is a high-response, two-stage electro-hydraulic servo valve engineered by EMG Automation for precision closed-loop control of position, velocity, force, and pressure in demanding industrial hydraulic systems. The unit operates on a nozzle-flapper, force-feedback torque motor principle: an electrical command signal drives the torque motor armature, which deflects the flapper between twin nozzles to modulate differential pilot pressure across the main spool. The resulting spool displacement is fed back mechanically to the torque motor, producing a high-resolution, hysteresis-free output flow proportional to the input current. With a rated operating pressure of 315 bar and an NG10 (Size 10) interface, this valve is purpose-built for fast, accurate actuation of cylinders and rotary actuators where dynamic response and repeatability are critical.
