Proportional Directional Valve 4WRZE25W8-325-7X/6EG24ETK31/A1D3M - Bosch Rexroth R900954678

On a new installation the number of ports often decides how much work the valve manifold takes. The 4WRZE25W8-325-7X/6EG24ETK31/A1D3M manages with internal pilot oil supply and internal return while delivering 325 l/min nominal flow at 350 bar.

Benefits

• Internal pilot control on feed and return, so the subplate needs no extra drillings.
• 325 l/min nominal flow against 870 l/min maximum flow.
• Analog ±10 V command at the on-board electronics with spool position feedback.
• The integrated pressure reducing valve protects the pilot stage at system pressure up to 350 bar.
• Spool symbol W8 with a defined centre condition, NBR seals for HL hydraulic fluid.

Applications

Aimed at newly designed valve manifolds in presses, special purpose machines and test rigs where piping should stay lean. Size 25 leaves reserve if the axis has to run faster later. UKCA conformity to SI2016/1091.
