The 4WRTE16E200L-4X/6EG24K31/A5M is a directional control valve in the 4WRTE Directional Control Valves series produced by Bosch Rexroth for hydraulic automation systems. It meters flow through a proportional spool that follows a linear characteristic, allowing predictable response across the stroke. The integrated electronics accept a ±10 V command and feedback signal so the valve position can be driven by common motion controllers. Electronics are powered from a 24 V DC supply, drawing up to 1.6 A and 72 VA under peak conditions, and they can operate continuously thanks to a 100 % relative duty cycle. Connection to the machine wiring is made through a plug that follows the EN 175201-804 standard, and the housing achieves an IP65 protection class to resist dust and water ingress during field installation. When properly supplied, the valve can pass up to 460 l/min, supporting high-flow actuator circuits.
The hydraulic section is rated for 350 bar on ports P, A, and B, while the external pilot return circuit is limited to 250 bar, ensuring stable operation in high-pressure machinery. Pilot oil is taken internally from the main pressure gallery and is returned externally, which simplifies inlet plumbing while keeping return contamination separate from the tank line. The mounting interface follows the ISO 4401-07-07-0-05 porting pattern so the unit can bolt directly to standard subplates without adapter blocks. Dynamic sealing is handled by NBR elastomers that are compatible with common mineral-oil fluids used in industrial power units. The assembled valve weighs 11.2 kg, providing sufficient mass for vibration resistance yet still allowing single-person handling during maintenance.
