Key Engineering Features
- Integrated digital electronics (OBE) with factory-calibrated spool position feedback for high repeatability and minimal hysteresis.
- High-response proportional solenoid with wet-pin armature design for precise force control and long service life.
- Progressive flow characteristic (E-type spool) enables smooth acceleration and deceleration of actuators.
- Rugged housing and precision-machined spool and sleeve assembly for minimal internal leakage and high contamination tolerance.
- Configurable command signal inputs (voltage or current) for direct interface with industrial PLC and motion controllers.
- Optional integrated pressure reducing valve and/or check valve functions available per model code.
- Compliant with ISO 4401-07 mounting interface for drop-in replacement in standard manifolds.
Industrial Applications
- Injection molding machines – clamp, injection, and ejector axis control.
- Hydraulic presses – force and position control in metal forming and stamping.
- Steel and aluminum rolling mills – roll gap and tension control.
- Marine and offshore – winch and crane motion control systems.
- Test rigs and simulators – high-dynamic servo-hydraulic actuation.
- Material handling – precise positioning of heavy loads in automated storage and retrieval systems.
