The 4WRTE16V1-200L-4X/6EG24ETK31/F1M valve is manufactured by Bosch Rexroth as part of the 4WRTE Directional Control Valves series and serves to meter hydraulic flow in automated machines. It occupies size NG16, allowing it to fit manifolds designed for mid-range flow rates, and attaches through the ISO 4401-07-07-0-05 mounting pattern to maintain interchangeability with standardized subplates. The spool follows a linear flow characteristic so that commanded displacement produces proportional flow, while the V1 spool symbol defines the specific port connections used during actuation. Spool position monitoring is included to send feedback to the controller for closed-loop accuracy. The valve draws pilot oil internally for both supply and return, reducing external piping, and withstands operating pressures up to 350 bar at ports P, A, and B for high-pressure circuits. A cleanliness level of ISO 4406 18/16/13 is required to protect the fine metering edges, and an IP65 housing prevents dust ingress and low-pressure water spray from affecting the electrical parts.
The device is powered from a nominal 24 V DC supply, and the F1 control electronics interface matches Rexroth amplifier cards that generate the command current. Maximum current consumption is limited to 1.6 A, resulting in a peak power draw of 72 VA that must be considered when sizing the power supply. A time-lag fuse rated at 4 A should be installed to disconnect the circuit during faults without nuisance trips at inrush. Return flow routed to port T can be handled safely up to 250 bar, supporting installations where back-pressure is present. The assembled valve weighs 11.2 kg, so mounting hardware must support that load without deflection. Together, these electrical and hydraulic ratings define safe operating limits and ensure reliable performance within automated hydraulic systems.
