Proportional Directional Valve 4WRZE10W6-25-7X/6EG24N9ETK31/F1D3M - Bosch Rexroth R901100109

Anyone who needs the spool of symbol W6 in the small flow step while managing without pilot lines will find the matching version in the 4WRZE10W6-25-7X/6EG24N9ETK31/F1D3M. 25 l/min nominal flow, a 4...20 mA current command value and an operating pressure of up to 315 bar define the working point.

Benefits

• Spool symbol W6, 25 l/min nominal flow, maximum flow up to 170 l/min.
• Internal pilot supply and internal draining, no X and Y lines required.
• Current command value 4...20 mA, on-board electronics, 24 VDC through a 7-pole connector (6 + PE).
• Concealed auxiliary actuation for emergency and maintenance movement.
• Operating pressure up to 315 bar, mounting pattern ISO 4401-05-05-0-05, weight 8.45 kg.
• NBR seals, hydraulic fluid HL, UKCA conformity.

Application

The variant makes sense on small control axes inside crowded manifolds, for example in clamping fixtures and adjusting units. Because the pilot stage is fed from port P, pressure has to be present there throughout the cycle. The return line carries the pilot flow as well.
