German-made Rexroth electromagnetic proportional hydraulic directional valves with electrical position feedback.
| 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) |
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.
Use IP67-rated protective covers, install the valve in a sealed enclosure, and regularly clean the valve body and solenoid coils.
Yes, they are designed to withstand vibration up to 10 g (10-2000 Hz) when mounted with vibration-damping washers.
Install a surge suppressor or accumulator in the system to absorb pressure spikes (limit spikes to ≤110% of the valve's maximum operating pressure).
Marine-grade models (with corrosion-resistant coatings) are available for saltwater environments; ensure compliance with marine safety standards (e.g., DNV GL).
Refer to manufacturer specifications for proper calibration procedures and adjustment parameters.
