Proportional Directional Valve 4WRGE16V125L-1X/210G24EK31/A1M - Bosch Rexroth R900939243
When return pressure builds up, pilot oil must not be dumped into the T line. This version takes pilot oil internally and returns it externally to tank. It meters 125 l/min at 350 bar, with internal spool position feedback and a ±10 V analog input.

Description
Circuits with raised return pressure need a separate, unloaded path for the pilot stage. That is what the 4WRGE16V125L-1X/210G24EK31/A1M is built for. It controls 125 l/min at up to 350 bar, taking pilot oil internally and discharging it externally through Y to tank.
Benefits
- External pilot oil return keeps the pilot stage independent of back pressure in the T line
- Internal pilot oil supply, so no additional X line has to be routed
- 125 l/min nominal flow, with the size rated up to 460 l/min
- Spool symbol V with internal position measurement, so position holds under changing load
- Four ports, three switching positions, 24 V DC supply
- Mass 10 kg, NBR seals, suitable for HL hydraulic fluid
Applications
The variant makes sense wherever filters, coolers or long return lines raise tank pressure. It is used in presses and in power units with a shared return manifold. The 125 l/min rating covers medium sized cylinders with margin to spare.
