Proportional Directional Valve 4WRZE10W6-25-7X/6EG24N9ETK31/A1V - Bosch Rexroth R978910857

The smaller the flow an axis needs, the more the spool rating matters. At 25 l/min nominal flow the 4WRZE10W6-25-7X/6EG24N9ETK31/A1V covers the lower end of size 10 and resolves travel commands accordingly, at operating pressures up to 315 bar.

Benefits

• 25 l/min nominal flow, giving fine resolution during approach and creep motion.
• Spool symbol W6, 3 switching positions and 4 ports, connection diagram ISO 4401-05-05-0-05.
• Internal pilot oil supply and internal pilot oil return save two control lines in the manifold.
• FKM seals and HL hydraulic fluid, 8.48 kg weight.
• On-board electronics taking a ±10 V command, 24 VDC through a 7-pole (6 + PE) connector to EN 175201-804.

Applications

The valve suits infeed and tracking axes, tool adjustment drives and test set-ups built around small cylinders. Because pilot oil runs internally, a standard manifold does the job and no separate X and Y lines are needed. The 170 l/min maximum flow stays available as reserve for rapid traverse phases.
