Key Engineering Features
- Two-stage pilot-operated design with integrated pilot control valve for high flow capacity and precise control.
- Electrical position feedback via inductive displacement transducer ensures high repeatability and minimal hysteresis.
- Progressive flow characteristic (W6 spool) enables fine control at low command signals and high flow at full stroke.
- Robust cast iron housing and hardened spool for long service life in continuous duty applications.
- Compatible with REXROTH proportional amplifier modules for closed-loop position, velocity, or force control.
- Optional integrated pressure reducing valve for pilot oil supply, reducing external piping requirements.
Industrial Applications
- Hydraulic presses and forming machinery requiring precise force and position control.
- Injection molding machines for accurate injection speed and pressure profiling.
- Steel and metal processing equipment with high dynamic response demands.
- Marine and offshore hydraulic systems with high flow and pressure requirements.
- Test rigs and simulation systems for aerospace and automotive component validation.
- Heavy-duty material handling and lifting equipment with proportional motion control.
