| 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) |
Yes, optional position feedback sensors (inductive or potentiometric) can be installed to monitor spool position and enable closed-loop control.
A bypass valve allows fluid to bypass the 4WREE during maintenance or emergency shutdowns, preventing system pressure buildup.
Yes, Rexroth offers IP65-rated protective covers for solenoid coils and electronics to shield against dust, moisture, and mechanical damage.
Yes, compact models (NG 6-10) are suitable for mobile equipment, provided they are protected from vibration and extreme temperatures (use shock mounts if needed).
Yes, their fast response time (15-50 ms) makes them ideal for high-speed applications such as robotic arms and conveyor systems.
