Vickers SV1-10 & SV1-06 Servo Valve | SV1-10/48/315/6 | SV1-10/8/100 | Direct Drive

Vickers Type SV1 Series High-Response Direct Drive Servo Valves

Product Overview:

The Vickers SV1 Series represents the pinnacle of direct-drive proportional servo valve technology. By eliminating the pilot stage, this series (available in Size 06 and Size 10) utilizes high-force proportional solenoids to actuate the spool directly. This Direct Drive architecture delivers servo-level dynamic response, minimal hysteresis, and superior positioning accuracy. From micro-flow precision in machine tools (e.g., SV1-06/05) to high-flow closed-loop control in heavy presses (e.g., SV1-10/48), the SV1 series ensures outstanding reliability at operating pressures up to 315 Bar.

Key Technical Advantages:

• Servo-Grade Dynamics: The direct-drive design eliminates pilot-stage lag, providing high frequency response bandwidth ideal for high-speed closed-loop systems.

• Comprehensive Pressure Ratings: Available in 100 Bar standard and 315 Bar high-pressure variants to suit diverse hydraulic requirements.

• Precision Zero-Lap Spool: Spool and sleeve assemblies are micro-ground for excellent linear output and exceptional repetitive positioning accuracy.

• Enhanced Contamination Resistance: Compared to pilot-operated servo valves, the direct-drive structure is more robust against oil particles, reducing maintenance costs.
