Key Features of YUKEN LSVHG-03EH-270-2-WEC-D2-20-SU

The YUKEN LSVHG-03EH-270-2-WEC-D2-20-SU servo valve integrates advanced linear motor technology, directly driving the spool with electric feedback of spool position—eliminating complex transmission structures and enhancing overall performance . Its core features include:

• High Responsiveness: Equipped with a compact and powerful linear motor, it achieves fast step response and frequency response (100Hz/-90° phase lag at ±25% input amplitude), making it ideal for high-speed control scenarios .
• Exceptional Contamination Resistance: The simplified structure (linear motor, moving coil, spool, and position sensor connected in series) ensures stable operation even in contaminated hydraulic oil, reducing maintenance frequency and extending service life .
• High Precision Control: With low hysteresis (≤0.1%) and high repeatability, it provides accurate control of position, velocity, pressure, and force, meeting the strict requirements of precision industrial equipment .
• Compact & User-Friendly Design: As an OBE type servo valve, it integrates an exclusive amplifier, reducing overall size and improving ease of installation and operation .
• Durability: Key components (spool, valve sleeve) undergo surface hardening treatment, ensuring long service life (over 1500 million cycles) even in high-load, continuous operation .
