Proportional Directional Valve 4WRZE10E85-7X/6EG24N9EK31/A1D3M - Bosch Rexroth R900760047

Back pressure in the tank line distorts the pilot stage if it drains there. The 4WRZE10E85-7X/6EG24N9EK31/A1D3M avoids this with internal oil pick-up and a separate drain through the Y port, metering 85 l/min nominal flow at up to 315 bar.

Benefits

• The spool carries symbol E and the nominal flow is 85 l/min.
• Internal pilot oil supply with external drain through Y, so tank pressure does not act on the pilot stage.
• A pressure reducing valve in the pilot stage caps control pressure, working pressure may reach 315 bar.
• On-board electronics process the ±10 V command value at the valve, powered by 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• Mounting pattern ISO 4401-05-05-0-05, NBR seals for HL fluid, maximum flow 170 l/min, weight 8.42 kg.
• UKCA conformity to SI2016/1091 covering electromagnetic compatibility.

Applications

The variant fits installations with return filters, coolers or long tank lines where return pressure rises noticeably. Through Y the pilot stage drains free of pressure and keeps its characteristic curve. For the main circuit a subplate to ISO 4401-05-05-0-05 is sufficient.
