Upgrade your hydraulic infrastructure and achieve absolute, servo-level motion control with the THM 4WRPEH10 Series Servo Solenoid Proportional Valve. Engineered for the most exacting fluid power applications, this direct-operated directional control valve combines a high-performance servo-quality spool and sleeve architecture with state-of-the-art On-Board Electronics (OBE). Delivering a nominal flow rate of 100 L/min while effortlessly sustaining maximum working pressures up to 315 bar, the 4WRPEH10 ensures perfectly metered, hysteresis-free fluid routing. Factory-calibrated and featuring a critical 4/4 fail-safe position, it is the ultimate precision upgrade for complex production lines, advanced testing systems, and the heavy-duty civil and road construction machinery that demands uncompromising accuracy.
Core Technical Specifications
- Valve Architecture: Direct Operated Servo Solenoid Directional Control Valve
- Model Series: THM 4WRPEH10 (Unit Series 2X)
- Maximum Working Pressure: Up to 315 bar
- Nominal Flow Rate: Up to 100 L/min (at Δp = 70 bar)

Key Features & Engineering Advantages
- Servo-Quality Precision: The internal control spool and sleeve are machined to strict servo-quality tolerances. This guarantees lightning-fast response times, minimal internal leakage, and the ultra-precise fluid metering required for highly sensitive hydraulic operations.
- On-Board Electronics (OBE): Features a built-in, factory-calibrated amplifier unit. This completely eliminates the need for external control cards, drastically simplifying machine wiring and ensuring perfect, plug-and-play synchronization on the assembly floor.
- 4/4 Fail-Safe Architecture: Operated on one side, the valve features a critical 4/4 fail-safe position. In the event of an electrical power loss or system shutdown, the valve automatically defaults to a secure switched-off state, instantly protecting your machinery and the job site.
- Versatile Signal Inputs: Equipped with a signal input differential amplifier, allowing engineers to easily interface with the valve using either standard "A1" (±10V) or "F1" (4...20mA) control signals, ensuring seamless integration with existing PLCs and testing computers.
- Heavy-Duty 315-Bar Resilience: Despite its highly sensitive electronic nature, the robust valve body is built to safely absorb continuous hydraulic hammering and the extreme 315-bar pressure spikes inherent in heavy industrial environments.
Ideal Industry Applications
The servo-level accuracy, factory-calibrated OBE, and fail-safe security of the 4WRPEH10 Series make it a mandatory automated component for:
- Production & Testing Systems: Providing the exact, highly repeatable fluid routing required for advanced hydraulic test benches, automated quality control rigs, and complex manufacturing lines.
- Heavy Civil & Road Machinery: Delivering the dynamic, precise motion control needed for automated leveling screeds, sensor-driven steering systems, and precision auxiliary attachments on large-scale asphalt pavers and road milling machines.
