Proportional Directional Valve 4WRZE32W6-520-7X/6EG24TK31/A1D3M - Bosch Rexroth R901125756

When an older valve is replaced, the signal level usually stays as it is. The 4WRZE32W6-520-7X/6EG24TK31/A1D3M therefore works with a plus or minus 10 V command, controls 520 l/min nominal flow at up to 350 bar and draws pilot oil from outside while returning it internally.

Benefits

• A plus or minus 10 V command matches existing analogue outputs without a signal converter.
• External pilot oil supply with internal return needs only 1 additional pilot line.
• The integrated pressure reducing valve keeps pilot pressure steady, independent of the 350 bar working pressure.
• Spool symbol W6 with 3 switching positions, nominal flow 520 l/min, maximum 1600 l/min.
• 7-pole connector (6 + PE) to EN 175201-804, 24 VDC, weight 43.6 kg, UKCA conformity.

Applications

The valve replaces aged proportional valves in presses, lifting gear and test rigs whose control system still works with analogue voltage. Because the pilot oil return runs internally, piping is shorter than with the fully external version. Mineral oil of class HL with NBR seals is intended.
