Proportional Directional Valve 4WRZE10E25-7X/6EG24N9K31/A1D3M - Bosch Rexroth R901233936

The 4WRZE10E25-7X/6EG24N9K31/A1D3M separates the pilot stage strictly from the main circuit: supply through X, draining through Y. At 25 l/min nominal flow and up to 315 bar operating pressure the spool of symbol E follows the +/-10 V voltage command value. A concealed auxiliary actuation supplements the electrical control.

Benefits

• External pilot supply and external draining, pilot pressure fully decoupled.
• 25 l/min nominal flow, maximum flow 170 l/min at 315 bar operating pressure.
• Concealed auxiliary actuation for emergency and set-up operation.
• Command value +/-10 V, on-board electronics with position feedback, 24 VDC.
• Spool symbol E, subplate mounting ISO 4401-05-05-0-05, weight 9.12 kg.
• NBR seals, hydraulic fluid HL, UKCA conformity.

Technical data

Application

This version is found in test fields and large plants with central pilot pressure supply in which a small axis is controlled precisely. Separating main and pilot circuit stabilises control behaviour. The auxiliary actuation allows the axis to be moved during set-up.
