Proportional Directional Valve 4WRZE25E220-7X/6EG24K31/A1D3M - Bosch Rexroth R901383440

When working pressure swings widely, pilot behaviour follows unless something prevents it. The 4WRZE25E220-7X/6EG24K31/A1D3M therefore carries its own pressure reducing valve and holds 220 l/min nominal flow on the command value at operating pressures up to 350 bar.

Benefits

• An integrated pressure reducing valve keeps pilot pressure constant even when working pressure jumps.
• 220 l/min nominal flow with spool symbol E and 3 switching positions in size 25.
• External pilot oil supply and external return for power units with their own pilot circuit.
• Plus or minus 10 V command into on-board electronics, 24 VDC at a 7-pole connector (6 + PE) to EN 175201-804.
• UKCA conformity to SI2016/1091, NBR seals, weight 20.6 kg.

Applications

The valve controls lifting and feed axes in presses and forming machines whose pressure changes strongly within a cycle. Thanks to the built-in pressure reducing valve, the characteristic curve stays comparable across the whole cycle. Range maximum flow reaches 870 l/min.
