Proportional Directional Valve 4WRZE32W9-360-7X/6EG24N9EK31/F1D3M - Bosch Rexroth R901280681

Where the pilot oil return has to be routed separately, for instance because of back pressure in the return line, this version fits: the 4WRZE32W9-360-7X supplies pilot control internally and returns it externally, at 360 l/min nominal flow and 350 bar operating pressure.

Key benefits

• External pilot oil return keeps pilot control free of back pressure in the main return line.
• 360 l/min nominal flow in size 32 gives finer resolution than the 520 l/min step.
• Built-in pressure reducing valve provides pilot pressure without a separate pump.
• 4 to 20 mA command value on a 7-pole connector to EN 175201-804.
• Concealed manual override for service work, protected against accidental operation.
• 44.24 kg, NBR seals, spool symbol W9, peak flow up to 1600 l/min.

Technical data

Applications

The version suits systems with long return lines or several consumers on a shared tank port, where back pressure would disturb the pilot circuit. The lower nominal flow fits axes with medium oil demand that still run on a size 32 manifold. Control is analog with a current signal, closed by the on-board electronics.
