The 4WRTE16E200L-4X/6EG24ETK31/A1V directional control valve is manufactured by Bosch Rexroth and belongs to the 4WRTE Directional Control Valves series. It regulates flow and pressure in hydraulic automation systems where proportional spool positioning is required. A nominal size of 16 defines the mounting envelope, while the ISO 4401-07-07-0-05 interface lets the valve bolt directly to standard subplates. Ports P, A, and B can operate at pressures up to 350 bar, and a maximum recommended flow of 460 l/min permits fast actuator movement. Pilot oil is supplied and returned internally under option ET, and the main stage is commanded by an NG6 solenoid pilot valve designated 6E. The integrated electronics accept a ±10 V command signal identified as code A1, presenting an input resistance of 100 kΩ to the motion controller. Normal operation requires a 24 V DC supply that powers the driver circuitry.
Electrical hookup is completed through a K31 connector that follows DIN EN 175201-804, simplifying field wiring. Peak current consumption is limited to 1.6 A, and total apparent power does not exceed 72 VA, so cabinet fusing can be sized accordingly. The valve provides a ±10 V measuring output that mirrors spool position for closed-loop feedback to the machine control. An IP65 protection class shields the housing against dust ingress and water jets, and FKM seal material supports operation with a wide range of hydraulic fluids. The assembly weighs 11.2 kg, which must be supported by the manifold and mounting hardware during installation.
