Original imported proportional electro-hydraulic directional valve manufactured by Rexroth in Germany.
| 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) |
Optimal viscosity is 20-40 mm²/s (cSt). Viscosity below 10 mm²/s may cause leakage, while viscosity above 100 mm²/s may increase pressure drop and reduce response time.
Yes, a 25 μm absolute filter (β100 ≥ 75) is mandatory in the supply line to prevent contamination of the valve's internal components.
Yes, water contamination (exceeding 0.1%) can cause corrosion, seal degradation, and clogging. Use water-separating filters and monitor fluid moisture levels.
Follow ISO 4406 Class 18/16/13 (maximum 1300 particles ≥4 μm, 160 particles ≥6 μm, 20 particles ≥14 μm per mL).
Yes, all 4WREE valves meet CE requirements for electromagnetic compatibility (EMC) and machinery safety (Directive 2006/42/EC).
