EMG SV1 SV2 Servo Valve | SV1-10/16/210/6 | SV1-10/4/100/6

LIC Hydraulic specializes in the EMG SV1 & SV2 Series, the gold standard in high-precision hydraulic servo valves for strip guiding systems. As the heart of EMG’s EPC (Edge) and CPC (Center) control loops, the SV series—including flagship models like SV1-10/16/210/6 and SV1-10/4/100/6—translates minute electrical commands into instantaneous, accurate hydraulic flow. Designed for the relentless environments of steel mills and aluminum plants, the EMG SV series features zero-dead-band technology and exceptional frequency response, ensuring that your strip material remains perfectly aligned even at maximum production speeds.

Technical Highlights

• Zero Dead-Band Control: Precision-lapped spool and sleeve assemblies ensure linear flow output from the very beginning of the command signal.

• Extreme Dynamic Sensitivity: Capable of processing high-frequency signals for millisecond-level adjustments in strip positioning.

• Industrial Durability: Rugged construction designed to withstand the vibration, heat, and contaminants common in heavy metallurgical processing.

• High Volumetric Efficiency: Optimized internal design minimizes internal leakage while maximizing control precision at pressures up to 210 bar.

Application Areas

• Steel Rolling Mills: Uncoiler and recoiler guiding in cold rolling, galvanizing, and pickling lines.

• Aluminum Industry: High-speed edge control for foil mills and slitting lines.

• Paper & Conversion: Reliable steering for continuous web processing and winding machines.

Expert Maintenance Tips

• Absolute Filtration Required: Servo valves are highly sensitive to microscopic debris. Maintain fluid cleanliness at ISO 16/14/11 to prevent spool erosion and sticking.

• System Flushing: Always use a flushing plate to clean the hydraulic circuit before installing a new SV1-10 valve. Never allow installation debris to pass through the servo valve.

• Electrical Integrity: Use high-quality shielded cables for the command signal to prevent electromagnetic interference (EMI) from industrial motors from affecting the valve’s accuracy.
