Product Advantages
1. 10ms Ultra-Fast Dynamic Response
With optimized direct-acting drive structure and high-sensitivity solenoid, the response time is controlled within 10ms - 3x faster than ordinary proportional valves. It delivers high-frequency dynamic flow regulation, perfectly matching the demands of high-speed test rigs and CNC precision feeding systems.
2. IO-Link Smart Control for Industry 4.0
The optional IO-Link digital interface enables real-time condition monitoring, remote parameter configuration and fault diagnosis. It supports safety shut-off function up to PL d / Category 3 per EN 13849-1, seamlessly integrating into smart hydraulic systems and automated production lines.
3. Servo-Class Micro-Flow Control Accuracy
The spool and sleeve are machined to servo-grade precision with micron-level matching clearance, achieving hysteresis below 0.1% and repeatability error under 0.05%. It ensures stable and linear control even at micro-flow conditions, meeting the strict requirements of high-precision manufacturing.
4. Zero Pilot Oil Demand & Fail-Safe Design
The all-in-one direct-acting structure eliminates the need for external pilot oil supply, reducing system energy consumption and maintenance points. The spring-centered spool provides automatic fail-safe reset upon power failure, improving system safety and reducing long-term operating costs.

FAQ
Q: Can this valve directly replace my Rexroth 4WRPEH6 C B24L-3X/M/24A1?
A: Yes. It follows the same ISO 4401 NG6 mounting standard with identical port size, ±10V A1 electrical interface and dynamic response performance. It can be installed directly without manifold modification.
Q: What is the core difference between 4WRPEH and 4WREE valves?
A: 4WRPEH features ultra-fast response within 10ms, servo-grade spool precision and optional IO-Link digital interface, designed for high-frequency and micro-precision scenarios. 4WREE is a general-purpose precision proportional valve with ＜30ms response for conventional industrial use.
Q: What functions does the optional IO-Link interface provide?
A: The IO-Link interface supports remote parameter setting, real-time operating status monitoring, fault diagnosis and safety shut-off function, helping users build smart digital hydraulic systems.
Q: What does PL d safety rating mean for this valve?
A: When equipped with IO-Link, the valve can be used as a safety shut-off element up to Category 3, Performance Level d according to EN 13849-1, meeting the safety requirements of medium-risk industrial machinery.
Q: What is the test condition for the rated flow?
A: The rated flow of 4–40 L/min is tested at Δp = 70 bar pressure drop, ensuring stable flow control even under high pressure difference conditions.
Q: What is the warranty and lead time?
A: We offer a 12-month quality warranty for all standard models. Standard 4WRPEH6 A1 configurations are delivered within 2–4 weeks after order confirmation.
