Features:
- High‑dynamic direct drive design powered by a permanent‑magnet linear force motor for rapid response and precise control
- Integrated closed‑loop spool position electronics ensure accurate, repeatable valve performance with low hysteresis
- Energy‑efficient 24 VDC PWM electronics reduce power consumption while delivering smooth, reliable operation
- Enhanced safety through spring‑centered fail‑safe design, ensuring the spool returns to neutral upon loss of power, a broken cable, or emergency stop conditions
