Proportional Directional Valve 4WRZE25W9-325-7X/6EG24N9ETK31/F1M - Bosch Rexroth R901404500

Where pilot pressure in the power unit is already limited, a lean pilot stage is enough. The 4WRZE25W9-325-7X/6EG24N9ETK31/F1M works with internal pilot oil supply, internal return and no pressure reducing valve of its own, at 325 l/min nominal flow.

Benefits

• Internal pilot oil supply plus internal return, no X or Y bore in the manifold
• Version without pressure reducing valve in the pilot stage, for an already controlled pilot pressure
• 325 l/min nominal flow in size 25, up to 870 l/min with the corresponding pressure drop
• Command value 4 to 20 mA on the on-board electronics, spool symbol W9 with three switching positions
• 20.4 kg weight, operating pressure up to 350 bar, NBR seals for HL hydraulic fluid

Applications

The valve is intended for presses, test rigs and power units with centrally controlled pilot pressure. The concealed manual override allows the axis to be moved while the electronics are down. Connection diagram ISO 4401-08-08-0-05, UKCA to SI2016/1091.
