Proportional Directional Valve 4WRZE32E520-7X/6EG24EK31/A1D3M - Bosch Rexroth R901058571

During a replacement the signal type counts as much as the symbol. The 4WRZE32E520-7X/6EG24EK31/A1D3M combines spool symbol E with a plus or minus 10 V command, controls 520 l/min at up to 350 bar and feeds pilot oil internally while the return is led away externally.

Benefits

• Spool symbol E with a plus or minus 10 V command replaces older valves without touching the control system.
• The integrated pressure reducing valve holds pilot pressure constant across the whole range up to 350 bar.
• Nominal flow of 520 l/min, maximum flow of 1600 l/min, 3 switching positions across 4 ports.
• Internal pilot oil supply with external return for tank lines that carry back pressure.
• 24 VDC at a 7-pole connector (6 + PE) to EN 175201-804, UKCA conformity, weight 43.74 kg.

Applications

The valve works in presses, forging plants and large handling axes with an existing analogue control system. Internal pilot supply saves one line while the external return keeps tank back pressure away from the pilot stage. The fluid is mineral oil of class HL, sealed with NBR.
