The 4WRE and 4WREE hydraulic proportional directional valves represent the pinnacle of fluid motion control, engineered to deliver absolute accuracy in the most rigorous industrial environments. When you handle these valves, the sheer weight of the robust cast iron housing and the flawless, cool-to-the-touch machined surfaces immediately convey a sense of industrial-grade durability. Every internal component is crafted to eliminate operational friction, allowing the control spool to glide silently and smoothly, directing hydraulic fluid with microscopic precision. The distinct, subtle click of the solenoids engaging confirms a rapid, latency-free response to your control system's commands, ensuring that your machinery moves exactly when and how you dictate.
Beyond their physical craftsmanship, these valves are designed to fundamentally transform how your heavy machinery operates. By eliminating erratic fluid surges and ensuring a continuous, metered flow, they protect your expensive hydraulic cylinders and motors from premature wear and catastrophic failure. The integration of high-grade FKM or NBR seals ensures that even under maximum pressure, there is zero weeping or fluid degradation, keeping your workspace pristine and your systems running at peak efficiency. Whether your equipment requires the subtle finesse needed for delicate material handling or the raw, controlled power necessary for heavy metal forming, these proportional valves provide the exact fluid delivery required to optimize your production cycles and drastically reduce costly machine downtime.

To assist you in making an informed procurement decision, we have compiled answers to the most common technical and operational inquiries regarding our proportional directional valves.
The core distinction lies in the electronic configuration. The 4WREE model features On-Board Electronics (OBE), meaning the amplifier is integrated directly into the valve for plug-and-play functionality. The 4WRE model requires a separate, external Eurocard amplifier to process the control signals, offering more flexibility for centralized control cabinets.
Yes, absolutely. Both the Size 6 and Size 10 variants are manufactured with mounting interfaces that strictly adhere to the ISO 4401 standard. This ensures a 100% seamless, drop-in replacement for original components without the need for adapter plates or manifold modifications.
The built-in LVDT (Linear Variable Differential Transformer) continuously monitors the actual physical position of the valve spool. If fluid resistance causes the spool to deviate from the commanded position, the feedback loop instantly detects this and corrects the current, ensuring ultra-precise flow control with less than 0.1% hysteresis.
Our valves are highly versatile and compatible with standard mineral-based hydraulic oils such as HL and HLP. Depending on the specific operating environment and fluid temperatures, you can select either NBR (Nitrile) seals for standard applications or FKM (Fluororubber) seals for higher temperatures and aggressive synthetic fluids.
We maintain a substantial inventory of standard configurations to ensure rapid deployment. For small to medium quantities, the lead time is typically between 1 to 15 days. For larger, customized OEM/ODM orders, our sales engineering team will provide a precise production schedule tailored to your specific requirements.
