Proportional Directional Valve 4WRZE32W6-520-7X/6EG24N9ETK31/A1D3M - Bosch Rexroth R901035732

If a plant runs at constant system pressure, a dedicated control oil pump is effort spent for nothing. The 4WRZE32W6-520-7X takes pilot oil internally, returning it the same way, while controlling 520 l/min nominal flow at 350 bar.

Benefits

• Internal pilot oil supply with internal return removes both the extra control oil pump plus the control lines.
• ±10 V command on 24 VDC, on-board electronics directly at the valve.
• 520 l/min nominal flow in size 32, flow limit 1600 l/min.
• Spool symbol W6, three switching positions, four ports.
• 350 bar operating pressure with NBR seals, HL hydraulic fluid, 44.02 kg.
• ISO 4401-10-09-0-05 interface, 7-pole connector (6 + PE) to EN 175201-804.

Application

It suits power units with a constant delivery pump plus pressure holding, on clamping fixtures, lift tables or feed axes. The version saves parts in the control circuit yet requires system pressure to stay safely above the pilot pressure. When needed, the spool can be shifted through the concealed auxiliary actuation.
