Proportional Directional Valve 4WRZE32W9-360-7X/6EG24N9EK31/A1D3V - Bosch Rexroth R901194990
If the system has no separate pilot pump, this 4WRZE saves the extra circuit: it takes pilot oil internally and carries the pressure reducing valve on board. In size 32 it meters 360 l/min nominal at 350 bar and accepts a ±10 V command. FKM seals suit demanding fluid and temperature conditions.

Description
A separate pilot circuit costs a pump, piping and space. This pilot-operated size 32 4WRZE proportional directional valve draws pilot oil internally from the main circuit and includes the pressure reducing valve. It meters 360 l/min nominal, passes up to 1600 l/min and works to 350 bar.
Benefits
- Internal pilot oil supply with an integrated pressure reducing valve removes the need for a separate pilot pump, pilot return is external.
- 360 l/min nominal and up to 1600 l/min maximum flow at 350 bar operating pressure.
- ±10 V command straight into the on-board electronics from an axis controller or analogue card.
- FKM seals instead of NBR, rated for HL hydraulic fluid.
- Concealed manual override supports commissioning and fault finding without power.
- ISO 4401-10-09-0-05 connection pattern, UKCA conformity under SI2016/1091.
Applications
Intended for presses, hydraulic power units and test rigs with high flow where no dedicated pilot circuit is to be built. The valve weighs 44.04 kg and is mounted on a subplate. Characteristic curves and pilot pressure limits are given in the data sheet.
Manufacturer
Bosch Rexroth, material number R901194990. Further data in the data sheet RE 29115 for the pilot-operated proportional directional valve and in catalogue RE 07600-B.
