Key Engineering Features
- Pilot-operated two-stage design with integrated pilot valve for high flow capacity and precise control.
- Proportional solenoid with wet-pin armature ensures low hysteresis and high repeatability.
- Spool position feedback via inductive position transducer for closed-loop control when used with appropriate amplifier.
- Spring-centered spool returns to neutral position upon power loss for fail-safe operation.
- Removable coil allows for easy maintenance without disturbing hydraulic circuit.
- Designed for use with external control electronics (e.g., Rexroth VT series amplifiers).
Industrial Applications
- Plastic injection molding machines – precise injection and clamping control.
- Metal forming presses – force and position regulation.
- Machine tools – feed and spindle actuation.
- Test rigs and simulators – dynamic motion control.
- Material handling – smooth acceleration and deceleration of heavy loads.
