Typical Applications
The 4WE6 series is engineered for high-frequency switching, heavy-duty reliability and long-term stability in demanding industrial hydraulic systems. It is widely used across manufacturing, processing and mobile machinery where consistent directional control performance and minimal downtime are critical.
- Hydraulic press machines - pressure and direction control
- Machine tooling - high-frequency spindle switching
- Automation lines - precise actuator logic control
Compatibility & Cross Reference
Direct drop-in replacement for Bosch Rexroth 4WE6 / 3WE6 series (WE6 ... /CG24N9Z5L and AW220N9Z5L coil variants). Same ISO 4401-03 mounting, no manifold modification required.
Mounting dimensions comply with NG6 / Cetop 3 / ISO 4401-03, following the same interface specification as the original manufacturer. Solenoid connector options, manual override positions and seal materials (NBR standard, Viton optional) match the original series, so spare-part interchange is straightforward.

Quality & Standards
YXCHK manufactures all 4WE6 valves in our Zhejiang factory (est. 1994) with 48 CNC machines and an annual output of 80,000+ sets. Each unit passes a 100% factory test covering electrical continuity, internal leakage and maximum working pressure, and is Intertek-certified for high-pressure reliability.
Mounting patterns follow the international ISO 4401 / DIN 24340 standard, dimensionally matching Bosch Rexroth and Yuken original series. Valves are backed by a 1-year replacement warranty and an 8-year design service life in standard industrial environments.
Frequently Asked Questions
Is the 4WE6 series 100% interchangeable with the original Rexroth 4WE6 series?
Yes. YXCHK 4WE6 valves use the identical mounting pattern (NG6 / Cetop 3 / ISO 4401-03), electrical interface and performance data as the original Rexroth 4WE6 series, so they drop into existing manifolds and systems without any modification, re-piping or redesign.
What is the maximum working pressure and flow of the 4WE6 series?
The 4WE6 series is rated at 31.5 MPa maximum working pressure with a maximum flow of 80 L/min. T-port back pressure is limited to 16 MPa.
Which coil voltages are available for 4WE6 valves?
DC 12/24V, AC 110/220V. Standard connectors are compatible with DIN 43650 / ISO 4400 plugs, and all coils are wet-type solenoid designs for extended service life.
What warranty and quality testing apply to 4WE6 valves?
Every valve is 100% factory tested (electrical continuity, internal leakage and max pressure) before shipment, Intertek-certified, and covered by a 1-year replacement warranty with 24/7 engineering support.
