BOKIN 4WREE Series Proportional Directional Valves
Direct-Acting | Integrated OBE | ISO 4401 Mounting
4WREE series are independently developed direct-operated proportional directional valves with electrical position feedback and on-board electronics (OBE). Designed for precise flow and direction control in industrial hydraulic systems, they match the mounting dimensions, electrical interfaces and hydraulic performance of equivalent Rexroth 4WREE configurations, supporting straightforward drop-in installation.
Available in NG6 and NG10 nominal sizes, with ±10V voltage and 4-20mA current loop control options, and multiple spool profiles to suit injection molding, die casting, metal forming and test bench applications.

Core Advantages of 4WREE Series
1.Rexroth-Compatible Mounting & Interfaces
Manufactured strictly to ISO 4401 standard mounting dimensions, with identical port positions and electrical pin assignments to equivalent Rexroth 4WREE valves. Direct drop-in installation requires no manifold modification, rewiring or circuit redesign, greatly reducing retrofit downtime and project costs.
2. Stable & Precise Control Performance
Integrated electrical position feedback and advanced OBE electronics deliver hysteresis below 0.1% and repeatability error under 0.05%. Excellent linearity and low temperature drift ensure consistent control accuracy across long operating cycles.
3. Flexible Configuration for Diverse Scenarios
Multiple spool options (standard zero overlap, overlapped, injection molding special) and two control signal types (voltage / current) are available. Custom spool profiles, special connectors and accessory kits can be supplied to match unique circuit requirements.
4. Reliable Quality & Fast Delivery
Every valve undergoes 100% full performance testing before shipment, backed by a 12-month global quality warranty. Standard models are available for fast delivery within 2–4 weeks, supporting both sample testing and bulk production orders.
