Rexroth Proportional Directional Control Valves 4WRPEH

Rexroth 4WRPEH proportional directional control valve

Description:

The Bosch Rexroth 4WRPEH series is a high‑response, direct‑operated proportional directional control valve with integrated electronics (OBE) and electrical position feedback. Designed to control both flow direction and flow magnitude, the 4WRPEH enables precise, stepless regulation of hydraulic actuators in modern electro‑hydraulic systems. With servo‑quality spool and sleeve, robust construction, and built‑in fail‑safe spool positioning, these valves deliver reliable, energy‑efficient performance in demanding industrial, test, and automation applications.

Rexroth Proportional Directional Control Valves 4WRPEH

  • High Precision & Repeatability — thanks to integrated electronics and electrical position feedback, the 4WRPEH achieves accurate, reproducible spool positioning and stable flow/pressure control with minimal hysteresis.

  • Fast Dynamic Response — direct‑operated design and servo‑quality spool/sleeve yield quick response to control signals, suitable for high-speed or frequent actuation requirements.

  • Energy Efficiency & Simplified Design — no need for pilot oil supply; onboard electronics (OBE) handle control, making installation simpler and reducing auxiliary fluid/energy demand.

  • Versatility (Position, Velocity, Pressure Control) — flexible enough for a range of applications: motion control, pressure regulation, actuator velocity control — useful in automation, test rigs, machine tools, forming / pressing machinery, etc.

  • Safety & Reliability (Fail-Safe + Robust Build) — in shutdown, the spool returns to a safe default position; durable materials and sealed electronics ensure long life even in demanding environments.

  • Compact & Modular (ISO / NG6 / ISO 4401 Pattern) — size variants (e.g. NG6) with standard ISO 4401 interface allow easy integration or replacement in existing manifold setups.
