Proportional Directional Valve 4WRZE25W6-325-7X/6EG24EK31/A1V - Bosch Rexroth R901066758

The 4WRZE25W6-325-7X/6EG24EK31/A1V serves axes that move several hundred litres per minute while being controlled by a plain ±10 V signal. The pilot stage works without a pressure reducing valve, takes its pilot oil internally and releases it through a dedicated Y line so that back pressure in the tank channel does not affect positioning accuracy.

Benefits

• 325 l/min nominal flow and a maximum flow rate of 870 l/min at up to 350 bar.
• External pilot return through Y keeps the pilot stage clear of back pressure in the tank.
• Pilot stage without a pressure reducing valve, with pilot oil taken internally.
• Spool symbol W6 with three switching positions and a ±10 V command value.
• FKM seals, a valve weight of 20.58 kg and mounting pattern ISO 4401-08-08-0-05.
