Proportional Directional Valve 4WRZE32E520-7X/6EG24N9EK31/A1D3M - Bosch Rexroth R901008504

In many plants that grew over the years the valve block has a drain line, though no control oil feed of its own. The 4WRZE32E520-7X is built exactly that way, taking pilot oil internally with an external return, while metering 520 l/min at 350 bar.

Benefits

• Pilot oil taken internally, returned externally matches manifolds that already have a drain line.
• Spool symbol E with three switching positions across four ports.
• 520 l/min nominal flow, size 32, flow limit 1600 l/min.
• ±10 V command, supply 24 VDC, electronics integrated at the valve.
• 350 bar operating pressure, NBR seals, HL hydraulic fluid, 43.92 kg.
• ISO 4401-10-09-0-05 interface, 7-pole connector (6 + PE) to EN 175201-804.

Application

The layout suits retrofits into existing valve stands where the drain line is already routed. Because the pilot return runs separately, switching time stays free of return pressure effects. Concealed auxiliary actuation is provided for setup work as well as faults.
