| Rexroth 4WERA Series Proportional Directional Control Valve |
|
| Overview |
|
| The Rexroth 4WERA is a high-performance, electrically controlled
proportional directional valve designed for precise flow control in
hydraulic systems. It combines advanced electro-hydraulic
technology with robust construction, making it ideal for industrial
and mobile applications requiring dynamic response and accuracy. |
|
| Key Features |
|
| • Proportional Control: Smooth and continuous adjustment of spool
position via electrical input signals (e.g., 0–10 V or 4–20 mA). |
|
| • High Precision: Linear relationship between input signal and
hydraulic flow rate/pressure. |
|
| • Versatile Configurations: Available in 4-way, 3-position or
2-position designs with various spool options (e.g., W, E, H). |
|
| • Pressure Ratings: Operates up to 350 bar (dependent on model),
suitable for demanding environments. |
|
| • Low Hysteresis: Ensures repeatable performance with minimal
deviation. |
|
| • Integrated Electronics: Some models feature onboard amplifiers
for simplified wiring (e.g., 4WRAE variant). |
|
| • Robust Design: Cast iron or aluminum housing for durability in
harsh conditions. |
|
| Typical Applications |
|
| • Industrial machinery (presses, plastic injection molding) |
|
| • Mobile equipment (cranes, agricultural vehicles) |
|
| • Test rigs and simulation systems |
|
| • Energy and wind turbine pitch control |
|
| Technical Specifications |
|
| • Mounting: ISO 4401 (CETOP 05/07) standard porting. |
|
| • Flow Capacity: Up to 120 L/min (model-dependent). |
|
| • Response Time: < 50 ms (typical). |
|
| • Protection Class: IP65 (dust/water resistant). |
|
| • Compliance: Meets ISO 9001 and industry safety standards. |
|
| Ordering Information |
|
| Model codes specify spool type, voltage, and options (e.g., 4WERA
10 E1-2X/G24K0/A1V). Consult datasheets for exact configurations. |
