Product Overview
The EMG SV 1-10/8/315/6 is a high-response electrohydraulic servo valve engineered by EMG (Elektro-Mechanik GmbH) for demanding closed-loop control applications in industrial hydraulic systems. Utilizing a precision two-stage nozzle-flapper pilot design with force feedback, this valve converts low-power electrical command signals into highly accurate, proportional hydraulic flow and pressure outputs. The SV 1-10 series is specifically designed for fast dynamic response, minimal hysteresis, and exceptional repeatability, making it the critical control element in systems requiring precise position, velocity, or force regulation of hydraulic actuators.

Engineering Features & Advantages
- Precision Performance: The nozzle-flapper pilot stage with mechanical force feedback delivers extremely high resolution, low hysteresis (<3%), and fast dynamic response, enabling accurate metering of flow and pressure in closed-loop servo control.
- Industrial Reliability: Constructed with hardened, precision-lapped spool and sleeve assemblies for long service life and consistent performance under continuous operation in severe industrial environments.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original EMG SV 1-10 series servo valves, ensuring drop-in replacement without modification to manifolds or control electronics.
- Stable Control Characteristics: The force-feedback torque motor design maintains stable gain and phase characteristics across the full operating pressure range up to 315 bar.
Typical Industrial Applications
This electrohydraulic servo valve is widely deployed in high-precision motion control systems, including plastic injection molding machines (clamp and injection axis control), metallurgical rolling mills and continuous casting equipment, hydraulic testing machines and fatigue test rigs, and CNC machine tool servo axes requiring precise position and force regulation.
