Information About 0811404662
The 0811404662 is part of Bosch Rexroth’s 4WRLE Series, engineered for proportional directional control with integrated onboard electronics (OBE). As a pilot operated valve with internal pilot oil supply and internal drain (ET configuration), it ensures stable performance in high-flow hydraulic circuits. The valve incorporates electrical feedback for continuous spool position monitoring, enhancing accuracy and repeatability in closed-loop applications. Designed in a 3X series construction with Buna-N (NBR) seals, it mounts to ISO 4401 Size 10 (D05 / NG10) subplates and operates with a 24 VDC supply using a ±10 V command input.
Key Features:
- 4-Way Pilot Operated Design: Enables precise directional control in high-capacity hydraulic systems.
- Integrated Electronics (OBE): Eliminates the need for an external amplifier for simplified installation.
- Electrical Position Feedback: Provides accurate closed-loop spool position control.
- Size 10 (D05 / NG10) Interface: Standardized mounting for manifold and subplate integration.
- ±10 V Command Signal (A1): Supports proportional control through analog input.
- 24 VDC Operation (G24): Compatible with standard industrial power supplies.
- Internal Pilot Supply & Drain (ET): Simplifies hydraulic circuit configuration.
- Buna-N (NBR) Seals: Suitable for use with mineral-based hydraulic oils.
The 0811404662 delivers the reliability and precision required for proportional directional control in advanced industrial hydraulic systems.
