BOKIN 4WRJE Series Proportional Directional Valves
Cost-Effective Pilot-Operated | Integrated OBE | Position Feedback
4WRJE series are independently developed pilot-operated proportional directional control valves with electrical position feedback and on-board electronics (OBE). Designed for stable flow and direction control in medium-to-large industrial hydraulic systems, they match the mounting dimensions, electrical interfaces and hydraulic performance of equivalent Rexroth 4WRJE configurations, supporting straightforward drop-in installation.
Available in NG10 to NG27 nominal sizes, with ±10V voltage control, multiple spool flow characteristics and pilot supply modes, to suit injection molding machines, die casting equipment, metallurgical machinery and new energy industry equipment.

Core Advantages of 4WRJE Series
1.Cost-Effective Pilot Control Solution
Two-stage pilot-operated structure delivers stable flow and direction control for medium-to-large hydraulic systems, with a more competitive price than high-pressure heavy-duty proportional valves. It is the optimal choice for conventional industrial scenarios that do not require 350 bar extreme pressure.
2. Stable Closed-Loop Position Control
Equipped with integrated OBE electronics and real-time electrical position feedback, it achieves closed-loop regulation with hysteresis ≤1% and response sensitivity ≤0.5%. The spring-centered main spool ensures safe reset when power is cut off, improving system operation stability and repeatability.
3. Standardized Design for Easy Integration & Maintenance
Manufactured strictly to ISO 4401 mounting standards with universal electrical interfaces, it can be seamlessly integrated into existing hydraulic systems. The simple and robust structure reduces daily maintenance difficulty and lowers long-term operation costs.
4. Flexible Configuration for Diverse Scenarios
Multiple spool flow characteristics and four pilot oil supply modes are available to match different circuit requirements. We also support custom spool profiles and accessory kits, fully adapting to various medium-pressure industrial hydraulic systems.
