Proportional Directional Valve 4WRZE32W8-520-7X/6EG24ETK31/A1D3M - Bosch Rexroth R900954701

Large axes are often retrofitted into existing manifolds where there is no room left for additional pilot lines. The 4WRZE32W8-520-7X feeds its pilot stage internally and returns it internally, at 520 l/min nominal flow and up to 1600 l/min maximum flow.

Benefits

• Nominal flow 520 l/min, maximum flow 1600 l/min
• Internal pilot oil supply and internal pilot oil return
• Pressure reducing valve in the pilot stage keeps pilot pressure constant
• Spool symbol W8 with 3 switching positions across 4 ports
• Command value ±10 V, on-board electronics, connector 7-pole (6 + PE)
• UKCA declaration SI2016/1091, ISO 4401-10-09-0-05 interface

Application

Used on presses, forging plant and large test rigs whose system pressure stays above the pilot pressure required. The installed weight of 43.6 kg calls for a lifting aid during replacement. NBR seals match mineral oil HL at up to 350 bar.
