Proportional Directional Valve 4WRZE10W6-85-7X/6EG24N9K31/A1D3M - Bosch Rexroth R900618374

Where pilot oil is generated centrally, the valve should draw from that source instead of the working circuit. The 4WRZE10W6-85-7X/6EG24N9K31/A1D3M is supplied and drained externally for exactly that, carries 85 l/min nominal flow with spool symbol W6 and works up to 315 bar.

Benefits

• Spool symbol W6 in size 10, 85 l/min nominal flow across 4 ports.
• External pilot oil supply and external pilot oil return separate the pilot circuit from the main circuit.
• A pressure reducing valve in the pilot stage caps control pressure, working pressure may reach 315 bar.
• Command value input ±10 V on the on-board electronics, wired through a 7-pole connector (6 + PE) to EN 175201-804 at 24 VDC.
• NBR seals, HL fluid, mounting pattern ISO 4401-05-05-0-05, maximum flow 170 l/min, 8.45 kg weight.
• UKCA conformity to SI2016/1091 covering electromagnetic compatibility.

Technical data

Applications

The variant is used in multi-axis installations fed from a shared pilot circuit, for example press lines and large test rigs. Control pressure stays constant even when working pressure collapses. X and Y have to be routed in the subplate.
