The 4WRLE16X200M-3X/G24EK0/A1M-812 belongs to the 4WRL Solenoid Valves series from Bosch Rexroth and is intended for precise hydraulic automation where electronic control of flow is required. It is built around nominal size 16 with a porting pattern that matches ISO 4401-07-07-0-05, allowing straightforward integration into standard subplates. A rated flow of 200 l/min enables stable circuit regulation during normal duty, while a supply voltage of 24 V DC powers the on-board electronics. The valve accepts a ±10 V analog command and presents an input impedance of 100 kΩ so that motion controllers experience minimal loading. Continuous service is supported by a 100 % duty cycle, and total power draw is limited to 40 VA to simplify power-supply selection. An IP65 protection class shields the coil and connectors from dust and water jets, keeping performance consistent in industrial environments.
The design supports a maximum flow of 800 l/min when fully actuated, giving headroom for transient peak demand. A minimum pilot pressure of 10 bar is required to shift the spool, ensuring positive movement even under low system pressure. To maintain signal fidelity, the permissible residual ripple on the supply is capped at 2.5 Vpp. Circuit protection is achieved with a 2.5 A time-lag fuse that tolerates brief inrush currents without nuisance trips. The solenoid surface may reach up to 120 °C, so external cooling measures must respect this thermal ceiling. Functional reliability is quantified by an MTTFd of 75 years, aligning with long-life machinery targets, and the assembly weighs 12 kg, which influences manifold support and handling requirements during installation.
