Proportional Directional Valve 4WRZE25W8-220-7X/6EG24K31/A1D3M - Bosch Rexroth R901096209

Anyone running several controlled axes off one shared pilot oil supply wants the same pilot logic on all of them. The 4WRZE25W8-220-7X/6EG24K31/A1D3M fits that scheme with external pilot oil supply, external return and 220 l/min nominal flow.

Benefits

• 220 l/min nominal flow covers feed and pressing axes of medium size.
• Fully external pilot control gives equal response times across all valves on a manifold.
• Analog ±10 V command at the on-board electronics, with no amplifier card in the cabinet.
• The integrated pressure reducing valve holds pilot pressure steady at system pressure up to 350 bar.
• Maximum flow 870 l/min, mounting pattern ISO 4401-08-08-0-05, NBR seals.

Applications

Proven in forming machines, clamping systems and hoists with several cylinders controlled in parallel. Spool symbol W8 gives the axis a defined centre condition at standstill. HL hydraulic fluid, UKCA conformity.
