Features:
- Directly driven by a proportional solenoid
- 4/4-way design including failsafe position reduces need for additional safety components
- Fully hardened spool and bushing provides high accuracy and wear resistance
- Electronics mechanically uncoupled from housing allows for high vibration resistance for longer service life and less machine downtime
- Next-generation electronics with digital core and energy efficient components lead to low thermal stress and long electronics lifecycle
- Optimized overlaps and clearances between spool and bushing deliver low internal leakage and high contamination resistance
- Electronics placed on the solenoid delivers compact design for minimum installation space
