Proportional Directional Valve 4WRZE10W8-85-7X/6EG24N9ETK31/A1D3V - Bosch Rexroth R900753834

Older control cards output voltage, older manifolds rarely offer spare control oil ports. The 4WRZE10W8-85-7X/6EG24N9ETK31/A1D3V serves both, running a ±10 V setpoint, internal piloting and 85 l/min nominal flow at 315 bar.

Benefits

• ±10 V setpoint - existing analogue cards remain in service.
• Internal pilot supply and internal return, no additional drilling on the manifold.
• 85 l/min nominal flow, 170 l/min maximum throughput, 315 bar operating pressure.
• Mass 8.44 kg, spool symbol W8, 3 switching positions, 4 ports.
• FKM seals, HL hydraulic fluid, UKCA conformity to SI2016/1091.

Applications

Recommended when upgrading existing hydraulic plant while leaving electrics and manifold untouched. The larger nominal size also shortens travel times against the 50 l/min version.
