Proportional Directional Valve 4WRZE25W6-220-7X/6EG24N9ETK31/A1V - Bosch Rexroth R901012695

The fewer bores a control manifold needs, the fewer sealing points it can lose. The 4WRZE25W6-220-7X/6EG24N9ETK31/A1V helps that layout because it draws and returns its pilot oil internally while metering 220 l/min nominal flow.

Benefits

• Internal pilot supply and internal return, the manifold needs no pilot bores to the outside.
• 220 l/min nominal flow, up to 870 l/min maximum flow, operating pressure up to 350 bar.
• Build without a pressure reducing valve in the pilot stage.
• Spool symbol W6, three switching positions on four ports, ISO 4401-08-08-0-05.
• Plus/minus 10 V command value, on-board electronics, concealed manual override.
• 20.3 kg, FKM seals, 7-pole connector (6 + PE) to EN 175201-804, UKCA conformity.

Application

The valve makes sense in compact control manifolds of presses and injection moulding machines where several axes sit side by side. Internal pilot supply assumes sufficient system pressure. FKM seals allow operation on the fire resistant fluids released by the manufacturer.
