Proportional Directional Valve 4WRZE25W6-325-7X/6EG24EK31/F1D3M - Bosch Rexroth R901051670

Short cycle times call for flow, while a loaded tank line calls for a pilot return of its own. The 4WRZE25W6-325-7X/6EG24EK31/F1D3M joins both, with 325 l/min nominal flow at up to 350 bar and pilot oil taken internally but discharged externally.

Benefits

• 325 l/min nominal flow noticeably shortens fast traverse and return stroke times.
• Internal supply with an external pilot return keeps the pilot circuit apart from back pressure.
• Spool symbol W6 works alike in both flow directions, matching motors and through-rod cylinders.
• A 4...20 mA command into on-board electronics, supply 24 VDC.
• Built-in pressure reducing valve, UKCA conformity to SI2016/1091, weight 20.64 kg.

Technical data

Applications

The valve serves drum drives, reels and presses running high cycle counts. Because pilot oil is taken from working pressure, that pressure has to stay present across the whole cycle. Range maximum flow reaches 870 l/min.
