Key Technical Advantages:

• Superior Dynamic Performance: Featuring advanced voice-coil or torque-motor actuators, these valves offer minimal hysteresis and high-frequency bandwidth, ensuring oscillation-free performance in high-speed position, velocity, and force-control applications.

• Precision-Mated Components: Spool and sleeve assemblies are precision-lapped to nanometer-level tolerances, providing extreme sensitivity to small signal inputs and effectively eliminating “dead-band” effects that destabilize control systems.

• Excellent Zero-Stability: Thermally symmetric design and specialized heat-treated housing materials ensure that the valve maintains its zero-point stability despite hydraulic or ambient temperature fluctuations, drastically reducing control drift.

• Robust Sealing System: High-performance metal-to-polymer composite sealing technology allows for high-pressure control duty while maintaining exceptionally low internal leakage, ensuring maximum energy efficiency for your system.

Application Areas:

• Advanced Machine Tools: Servo-drive control for 5-axis high-precision machining centers.

• Industrial Robotics: Precise power control and multi-axis coordination for robotic manipulators.

• Aerospace Simulation: Hydraulic drive systems for 6-DOF motion simulators.

• Precision Metallurgy: Automatic Gauge Control (AGC) for strip steel production and continuous casting systems.

Expert Maintenance Tips:

• Strict Filtration Requirements: Servo valves are highly sensitive to microscopic debris. A 3μm precision filter is mandatory, and system fluid cleanliness must be strictly maintained at ISO 4406 15/13/11.

• Electrical Signal Management: Ensure a clean, stable power supply from your servo controller and use shielded cables for valve connections to prevent EMI (electromagnetic interference) from causing valve chatter or drift.

• Mounting & Protection: Install on a flat, stress-free subplate to prevent valve body deformation. Ensure all electrical connections are sealed against moisture, as corrosion of internal electronic components is a leading cause of long-term failure.
