Proportional Directional Valve 4WRZE25E1-325-7X/6EG24ETK31/F1D3M - Bosch Rexroth R901131625

A pilot-operated directional valve only works reliably while pilot pressure stays inside its window. The 4WRZE25E1-325-7X/6EG24ETK31/F1D3M solves this with an integrated pressure reducing valve while handling 325 l/min nominal flow at 350 bar operating pressure.

Benefits

• The integrated pressure reducing valve holds pilot pressure steady even as system pressure climbs to 350 bar.
• 325 l/min nominal flow against 870 l/min maximum flow, sized for large cylinders.
• Spool symbol E1 offers a defined centre condition for axes that are unloaded at standstill.
• A 4 ... 20 mA command stays clean in plants with long cable runs and powerful drives.
• Internal pilot oil supply and internal pilot oil return remove the need for extra pilot lines.
• UKCA conformity including electromagnetic compatibility to SI2016/1091.

Applications

Intended for presses, rolling mills and test rigs at high system pressure where pilot control should not need separate protection. The valve weighs 20.58 kg and sits on an ISO 4401-08-08-0-05 pattern. UKCA conformity eases delivery of machinery into the United Kingdom.
