Proportional Directional Valve 4WRZE25E1-220-7X/6EG24N9ETK31/A1D3M - Bosch Rexroth R901094997

A tool that closes fast and then builds pressure gently needs its own pilot pressure stage at the directional valve. The 4WRZE25E1-220-7X/6EG24N9ETK31/A1D3M has an integrated pressure reducing valve, controls 220 l/min nominal flow at 350 bar and weighs 20.5 kg.

Advantages

• Integrated pressure reducing valve for its own, reduced pilot pressure stage.
• 220 l/min nominal flow at 350 bar operating pressure, maximum flow 870 l/min.
• Internal pilot oil supply and internal return without extra external piping.
• Analog command value ±10 V with on-board electronics, 24 VDC supply.
• Concealed auxiliary actuation for a functional check without an electrical signal.
• 20.5 kg weight, spool symbol E1, NBR seals, UKCA conformity to SI2016/1091.

Applications

The integrated pressure reducing valve allows a reduced pilot pressure stage independent of the main pressure, for example when a tool sets down gently before the actual pressure build-up. The concealed auxiliary actuation allows a functional check at commissioning. It suits applications with repeating cycles such as mold clamping units or press tooling.
