Proportional Directional Valve 4WRZE10E85-7X/6EG24EK31/A1D3M - Bosch Rexroth R901072867

Running a press axis under position control calls for a spool that meters 85 l/min cleanly across three switching positions. The pilot-operated 4WRZE10E85-7X/6EG24EK31/A1D3M does so up to 315 bar operating pressure, takes its pilot oil from the main circuit and passes the pilot oil return to the outside.

Benefits

• Nominal flow 85 l/min in size 10, the maximum flow reaches 170 l/min.
• Maximum operating pressure 315 bar across four ports to connection diagram ISO 4401-05-05-0-05.
• Integrated pressure reducing valve in the pilot circuit, plus internal pilot oil supply without a separate feed line.
• On-board electronics on 24 VDC with an analog ±10 V command value, no external amplifier card required.
• Spool symbol E with three switching positions, 8.44 kg weight, NBR seals for HL hydraulic fluid.

Applications

Typical installations are press axes, drawing lines and test rigs whose cylinders take up sizeable oil volumes in a short time. The subplate mounting to ISO 4401-05-05-0-05 fits size 10 control manifolds. Because the pilot oil return leaves the valve externally, the pilot circuit stays clear of back pressure in the main return line.
