The 4WRTE16V200L-4X/6EG24ETK31/A1V is a proportional directional control valve in the 4WRTE Directional Control Valves series from Bosch Rexroth. It regulates flow and pressure in hydraulic automation circuits using a closed-loop pilot stage and integrated electronics. The unit mounts to manifolds with the ISO 4401-07-07-0-05 interface, allowing direct substitution in standard subplates. A nominal supply voltage of 24 V DC powers the electronics, while operation remains stable between 18 V DC and 35 V DC to accommodate supply variation. Current draw reaches 1.6 A at peak demand, so power distribution must be sized accordingly. Command signals are accepted through a ±10 V analog interface identified as code A1, and the DIN EN 175201-804 plug designated K31 provides the electrical connection. Internal pilot oil supply and return simplify plumbing because no external lines are required.
The valve achieves a recommended flow capacity of 460 l/min for high-volume actuator control, and it withstands operating pressures up to 350 bar on ports P, A, and B. Maximum hysteresis is limited to 0.1 percent, ensuring accurate spool positioning during load reversals. Electronic modules tolerate residual ripple up to 2.5 Vpp on the supply, protecting control accuracy against power noise. The enclosure carries an IP65 rating so it resists dust and water jets when the connector is tightened. FKM seals are used to handle common hydraulic fluids and elevated temperatures, and the assembled unit weighs 11.2 kg, which must be supported by the manifold or mounting hardware.
