At 50 l/min nominal flow the 4WRZE10W8-50-7X/6EG24ETK31/A1D3M sits in the middle of size 10 and does without dedicated pilot lines. The +/-10 V voltage command value is turned into spool position symbol W8 by the on-board electronics, and operating pressure reaches 315 bar.

Benefits

• 50 l/min nominal flow, maximum flow up to 170 l/min.
• Internal pilot supply and internal return limit piping to four ports.
• Command value +/-10 V, on-board electronics with internal position feedback, 24 VDC.
• Spool symbol W8, 3 switching positions, operating pressure up to 315 bar.
• Subplate mounting to ISO 4401-05-05-0-05, weight 8.46 kg.
• Pressure reducing valve in the pilot stage, NBR seals, UKCA conformity.

Application

This version covers standard duties in machine tools and plastics machinery, such as controlled infeed and force build-up through the command value. Sufficient pressure in port P, from which the pilot stage is fed, is a precondition. The return line carries the pilot flow as well.
