Proportional Directional Valve 4WRZE10E50-7X/6EG24EK31/A1V - Bosch Rexroth R901286297

Hot oil and aggressive additives attack NBR seals, which is why this version carries FKM. The 4WRZE10E50-7X/6EG24EK31/A1V meters 50 l/min nominal flow with spool symbol E at operating pressures up to 315 bar, drawing pilot oil internally and draining it externally through Y.

Benefits

• 50 l/min nominal flow with spool symbol E, 4 ports and 3 switching positions.
• Internal pilot oil supply with external drain through Y, so tank pressure does not act on the pilot stage.
• This version carries no pressure reducing valve in the pilot stage, operating pressure reaches 315 bar.
• The ±10 V command value feeds the on-board electronics directly, supplied with 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• Hole pattern ISO 4401-05-05-0-05 to ISO 4401, FKM seals for HL fluid, 170 l/min maximum flow at 8.48 kg.
• UKCA conformity to SI2016/1091 covering electromagnetic compatibility.

Technical data

Applications

The valve goes into plants running at elevated oil temperature, for example die casting machines, hot forming presses and continuously loaded test rigs. With no pressure reducing valve fitted, the installation itself has to keep pilot pressure within the permitted range. The Y drain keeps return pressure away from the pilot stage.
