BOKIN 4WRAE Series Proportional Directional Valves
Direct-Operated | Integrated OBE | ISO 4401 Mounting
4WRAE series are independently developed direct-operated proportional directional valves with integrated on-board electronics (OBE) and spring-centered control spool. Designed for precise flow direction and flow rate control in compact hydraulic systems, they match the mounting dimensions, electrical interfaces and hydraulic performance of equivalent Rexroth 4WRAE 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 E/W spool profiles to suit injection molding auxiliary equipment, precision test benches and light-duty industrial hydraulic applications.

Core Advantages of 4WRAE 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 4WRAE valves. Direct drop-in installation requires no manifold modification, rewiring or circuit redesign, greatly reducing retrofit downtime and project costs.
2. Stable Proportional Control Performance
Integrated OBE electronics and spring-centered spool deliver smooth stepless flow regulation with reliable repeatability. Progressive flow characteristics minimize hydraulic impact, ensuring stable speed and pressure control for small precision hydraulic systems.
3. Flexible Configuration for Diverse Scenarios
Multiple spool options (standard E type, overlapped W type) 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.
