German-made electromagnetic directional valve by Rexroth.
| Selection Dimension | Specific Parameters/Options | Description |
|---|---|---|
| Model Designation | 4WRE | Basic model: Direct-acting proportional directional valve with electrical position feedback and no integrated electronics (OBE) |
| Integrated Electronics (OBE) | No Code | Standard configuration without integrated electronics; external amplifier required (to be ordered separately) |
| Nominal Size | 6 | Core size with component series 2X; mounting dimensions comply with Series 20-29 standards |
| Valve Core Type | 4/2 (2-position 4-way), 4/3 (3-position 4-way) | 4/3 type features spring-centered spool for automatic reset when de-energized; suitable for different oil circuit directional control needs |
| Rated Flow (Δp=10bar) | 4L/min (Code 04), 8L/min (Code 08), 16L/min (Code 16), 32L/min (Code 32) | Flow rates distinguished by corresponding codes; matched to hydraulic system flow requirements |
| Seal Material | V (FKM Fluororubber) | Default FKM material; compatible with mineral oil and other hydraulic fluids to ensure sealing performance |
| Power Supply Voltage | G24 (DC 24V) | Suitable for industrial standard DC power supply; meets proportional solenoid drive requirements |
| Electrical Interface | A1 (±10V Voltage Input), F1 (4-20mA Current Input) | Two interface options available; compatible with PLCs, computers, and other control signal sources |
| Electrical Connection | K4 (No Plug) | Plug compliant with DIN EN 175301-803 standard required (to be ordered separately) |
| Special Protection | J (Seawater-Resistant) | Only available for Size 6; suitable for marine-related or humid/corrosive working conditions |
| Mounting Standard | ISO 4401 | Panel mounting with standard mounting hole pattern; compatible with universal hydraulic system manifold layouts |
| Maximum Working Pressure | 315bar | Suitable for most medium-to-high pressure industrial hydraulic scenarios (e.g., hydraulic actuators in machine tools, automated production lines) |
Hysteresis is typically ≤3% of the full-scale control signal, ensuring precise and repeatable flow regulation.
The minimum operating pressure is 2 bar (29 psi) to ensure proper spool actuation and prevent cavitation.
Operating temperatures between -20°C and +80°C (-4°F to +176°F) are optimal. Temperatures outside this range may reduce response time or damage seals and electronics.
Cv values range from 0.8 (NG 6) to 12.0 (NG 25), indicating the valve's capacity to flow fluid at a given pressure drop (higher Cv = higher flow rate).
Yes, their low hysteresis and fast response make them ideal for closed-loop systems, paired with position or pressure feedback sensors.
External amplifier required for operation (to be ordered separately). Plug compliant with DIN EN 175301-803 standard required for electrical connection.
