4WRTE16V200L-4X/6EG24K31/A5M

The 4WRTE16V200L-4X/6EG24K31/A5M directional control valve belongs to the 4WRTE Directional Control Valves series and is produced by Bosch Rexroth for servo-controlled hydraulic circuits. It modulates spool position with an integrated proportional solenoid to manage flow and pressure in automated machinery. The valve is built in nominal size 16, allowing compatibility with medium-frame manifolds. It mounts on an ISO 4401-07-07-0-05 interface, so the port pattern matches standard subplates. Electrical supply is 24 V DC, while an acceptable input range of 18 V DC to 35 V DC prevents shutdown from minor line variations. A 4 A time-lag fuse protects the power line against short-term surges, and the electronics draw a maximum of 1.6 A during full actuation, keeping panel wiring relatively light. Peak power demand is limited to 72 VA, supporting use with compact power supplies. The coil can tolerate temperatures up to 150 °C, safeguarding the winding during extended duty cycles. With a protection class of IP 65 when the mating connector is fitted, the enclosure resists dust ingress and water jets, and the complete unit weighs 11.2 kg for manageable handling during installation.

Hydraulic ratings enable the valve to handle demanding circuits: ports P, A, and B operate safely up to 350 bar, letting the assembly control high-pressure actuators. Return oil routed through port T may reach 250 bar, so back-pressure in closed-loop systems does not compromise function. The main stage supports a maximum recommended flow of 460 l/min, providing adequate capacity for large cylinder groups. Pilot performance is tuned for responsiveness; stepping the command from 0 % to 100 % at 315 bar needs only 14 l/min of pilot oil, and the stroke consumes 2.9 cm³, which minimizes energy loss in the pilot circuit. These parameters allow fast spool movement without excessive power draw, ensuring stable positioning in servo loops. Combined, the pressure, flow, and pilot data define the hydraulic envelope in which the valve can regulate direction and speed of fluid actuators in industrial automation.
