Proportional Directional Valve 4WRZE10E85-7X/6EG24N9EK31/A1V - Bosch Rexroth R900959831

An established manifold often has only the Y drilling in place while the X line is missing. The 4WRZE10E85-7X/6EG24N9EK31/A1V fits that situation, takes pilot oil internally and drains it externally, metering 85 l/min nominal flow at operating pressures up to 315 bar.

Benefits

• Internal pilot oil supply with external pilot oil return, making use of the existing Y line.
• 85 l/min nominal flow, maximum flow 170 l/min in size 10.
• Spool symbol E, 3 switching positions and 4 ports, connection diagram ISO 4401-05-05-0-05.
• ±10 V command value on the on-board electronics, 24 VDC through a 7-pole (6 + PE) connector to EN 175201-804.
• FKM seals for HL hydraulic fluid, 8.01 kg weight.

Applications

The valve replaces actuators in existing manifolds of presses, saws and forming lines without any redrilling. At 85 l/min the cycle time of the axis stays close to the original design. Concealed auxiliary actuation serves the function check after the swap.
