Proportional Directional Valve 4WRZE10E25-7X/6EG24N9ETK31/A1D3M - Bosch Rexroth R900963799

The 4WRZE10E25-7X/6EG24N9ETK31/A1D3M controls small flows of 25 l/min through the spool of symbol E and the +/-10 V voltage command value. Pilot oil supply and draining both run internally, so only P, T, A and B need piping. Operating pressure reaches 315 bar.

Benefits

• 25 l/min nominal flow, maximum flow 170 l/min at 315 bar operating pressure.
• Internal pilot supply and internal draining, no separate pilot circuit required.
• Command value +/-10 V, on-board electronics with internal position feedback, 24 VDC.
• Concealed auxiliary actuation for movement without control voltage.
• Spool symbol E, 3 switching positions, mounting pattern ISO 4401-05-05-0-05.
• Weight 9.14 kg, NBR seals, hydraulic fluid HL, UKCA conformity.

Application

The variant is applied in fine positioning and force control inside machines with limited space. Port P must carry pressure throughout the movement because the pilot stage is fed from it. Low back pressure in the return line keeps control behaviour steady.
