Proportional Directional Valve 4WRZE10E25-7X/6EG24N9ETK31/F1D3M - Bosch Rexroth R901110779

The 4WRZE10E25-7X/6EG24N9ETK31/F1D3M needs neither a pilot pressure line nor a separate pilot return: both run internally. The 4...20 mA current command value drives the spool of symbol E at 25 l/min nominal flow and an operating pressure of up to 315 bar. A concealed auxiliary actuation is fitted.

Benefits

• Internal pilot supply and internal draining, connection only through P, T, A and B.
• 25 l/min nominal flow, maximum flow 170 l/min at 315 bar operating pressure.
• Current command value 4...20 mA on on-board electronics, 24 VDC supply.
• Concealed auxiliary actuation for movement without control voltage.
• Spool symbol E, 3 switching positions, mounting pattern ISO 4401-05-05-0-05.
• Weight 8.45 kg, NBR seals, pressure reducing valve in the pilot stage, UKCA conformity.

Application

The variant suits compact control manifolds in which every drilling counts. Small positioning axes and force control in special purpose machines are typical duties. Permanent pressure in port P and low back pressure in the return line are preconditions.
