Made in Germany and imported from 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) |
Common spares include solenoid coils, seal kits (O-rings, backup rings), filter elements, manual override caps, and integrated electronics modules.
Solenoid coils have a shelf life of 5 years if stored in a dry, cool environment (10-30°C, relative humidity ≤60%) and protected from dust and corrosion.
Non-Rexroth parts may not meet quality standards and can void the valve's warranty. Use only genuine Rexroth spare parts for optimal performance and safety.
Order via Rexroth's official website, authorized distributors, or customer service, providing the valve's part number and serial number (if available).
For temperatures below -20°C, use low-temperature hydraulic fluid (ISO VG 10) and heated reservoirs to prevent fluid thickening. Some models offer cold-start protection as an option.
