Rotary Direct Drive Servo Valve | Vickers SV1-10/48/315 | SV1-10/16/315 | EMG-20APB22

Rotary Direct Drive Servo Valves – Vickers SV1-10 & EMG Series

Product Overview:

Rotary Direct Drive Servo Valves represent the high-performance benchmark in hydraulic control technology. Unlike traditional pilot-operated structures, this series (including Vickers SV1-10 and EMG-20APB22) utilizes a high-power rotary motor to actuate the spool directly, completely eliminating the lag and clogging risks associated with pilot oil circuits. This design maintains exceptional dynamic frequency response under pressures up to 315 Bar, making it the primary choice for closed-loop control in injection molding machines, blow molding equipment, and high-performance industrial presses.

Featured models on this page: High-flow SV1-10/48/315/1, high-response SV1-10/16/315/9, and precision rotary servo specification EMG-20APB22.

Key Technical Advantages:

• Rotary Direct Drive Technology: The motor provides direct torque to the spool for instantaneous response, with a frequency response bandwidth far exceeding conventional proportional valves.

• Enhanced Contamination Resistance: The absence of fine pilot orifices makes this series more robust against oil particles, significantly improving reliability in harsh environments.

• High Pressure & High Flow Control: Supports full 315 Bar operation with flow rates ranging from 16 L/min to 48 L/min to meet diverse power output requirements.

• Precision Null Control: Micro-ground spool and sleeve assemblies ensure minimal deadband, providing high stability during both static holding and dynamic switching.
