BOKIN 4WRPE Series Proportional Directional Valves

Direct‑Acting | Integrated OBE | Electrical Position Feedback | ISO 4401 Mounting

4WRPE series are direct‑operated proportional directional valves with electrical position feedback and on‑board electronics (OBE). No pilot oil supply is required, delivering energy‑efficient, compact and precise flow, direction, position and velocity control for industrial hydraulic systems. Designed to match the mounting dimensions, electrical interfaces and hydraulic performance of equivalent Rexroth 4WRPE configurations, supporting straightforward drop‑in installation.

Available in NG10 nominal size, with ±10 V voltage, 4‑20 mA current loop and IO‑Link digital control options, and rich spool profiles including standard E/E1/W6/W8/V/EA and special Q3/Q5 spools to suit injection molding, die casting, material testing and compact automation applications.

Core Advantages of 4WRPE 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 4WRPE 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 0.25% 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, progressive Q3/Q5) 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.

FAQ

Q: Are BOKIN 4WRPE valves compatible with Rexroth 4WRPE series installations?

A: Yes. BOKIN 4WRPE valves are independently developed products designed to match ISO 4401 mounting dimensions, port sizes, electrical interfaces and hydraulic performance of equivalent Rexroth 4WRPE configurations. They support direct drop‑in installation in compatible systems. We recommend sharing your full model code for suitability confirmation.

Q: What is the difference between A1, F1 and L1 control interfaces?

A: A1 (±10 V) offers higher control precision for short‑wiring precision equipment. F1 (4‑20 mA) has stronger anti‑interference performance for long‑distance transmission. L1 (IO‑Link) supports digital communication, parameter setting and safety shut‑off functions for smart hydraulic systems.

Q: What are Q3 and Q5 special spools used for?

A: Q3 and Q5 are progressive‑flow special spool profiles with optimized flow gain characteristics, typically used in injection molding and precision speed control scenarios requiring smooth flow regulation. Custom spool profiles can be developed on request.

Q: Does the 4WRPE series require pilot oil supply?

A: No. 4WRPE is a direct‑operated proportional valve with no pilot oil circuit needed, simplifying system design and reducing energy consumption and maintenance points.
