Core Advantages of 4WRPEH Series

1. Ultra-Fast Servo-Grade Dynamic Response

Optimized magnetic circuit and lightweight spool design achieve step response within 10ms, delivering high-frequency dynamic flow regulation. It perfectly matches the demands of high-speed test rigs, CNC feeding systems and precision automation equipment.

2. Hassle-Free Direct Replacement

Manufactured strictly to ISO 4401 standard mounting dimensions, with identical port positions and electrical pin assignments to equivalent Rexroth 4WRPEH valves. Direct drop-in installation requires no manifold modification, rewiring or circuit redesign, greatly reducing retrofit downtime and project costs.

3. Optional Smart IO-Link Function

The optional IO-Link digital interface supports real-time condition monitoring, remote parameter configuration and fault diagnosis. It can be used as a safety shut-off element up to Category 3, PL d per EN 13849-1, seamlessly integrating into Industry 4.0 smart hydraulic systems.

4. Flexible Configuration for High-Demand Scenarios

Multiple spool flow characteristics (standard, linear, progressive, degressive) and two control signal types are available. Custom spool profiles, special electrical interfaces, and complete accessory kits can be supplied to match unique circuit requirements.

FAQ

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

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

Q: What is the core difference between 4WRPEH and 4WREE valves?

A: 4WRPEH features ultra-fast response within 10ms and servo-grade spool precision, designed for high-frequency dynamic and micro-precision scenarios. 4WREE is a general-purpose precision proportional valve with <30ms response for conventional industrial use.

Q: Does 4WRPEH series support IO-Link digital interface?

A: Yes. IO-Link interface is available as an optional configuration, supporting remote parameter setting, condition monitoring and safety shut-off function up to Category 3, PL d per EN 13849-1.

Q: What spool flow characteristics are available for 4WRPEH series?

A: Four spool profiles are available: standard (C), linear (C1), progressive (C3) and degressive (C4), with both linear (L) and inflected (P) flow curves. They can be selected according to different control requirements of speed, pressure and position.

Q: What is the test condition for the rated flow of 4WRPEH valves?

A: The rated flow of 4WRPEH series is tested at Δp = 35 bar per control edge. The actual flow under different pressure differentials can be calculated with the standard flow-pressure drop formula.

Q: Does 4WRPEH series support on-site zero point calibration?

A: Yes. All 4WRPEH valves are pre-calibrated at the factory with ±1% zero deviation. They are also equipped with an external zero adjustment screw, allowing on-site fine calibration without disassembly.
