Proportional Directional Valve 4WRZE10W6-25-7X/6EG24N9ETK31/A1D3V - Bosch Rexroth R978009885

On a retrofit in an existing plant every additional pipe means work. The 4WRZE10W6-25-7X/6EG24N9ETK31/A1D3V routes its control oil entirely internally, controls 25 l/min nominal flow and blocks in mid position with spool symbol W6.

Benefits

• Internal pilot oil supply and internal return, mounting solely through ISO 4401-05-05-0-05.
• 25 l/min nominal flow in size 10 at operating pressures up to 315 bar.
• Spool symbol W6 blocks in mid position and holds a standing load.
• Integrated pressure reducing valve in the pilot circuit, plus or minus 10 V command at the on-board electronics.
• FKM seals for mineral oil of class HL, concealed auxiliary actuation, weight 8.48 kg.

Applications

The valve is used on clamping axes, on flaps and on small lifting cylinders with a suspended load. Nominal flow of 25 l/min keeps motion controllable even over short strokes. Through electrical position feedback the spool follows the command without an extra control card.
