Proportional Directional Valve 4WRZE25W6-325-7X/6EG24N9TK31/A1M - Bosch Rexroth R901020002

In plants with a central pilot pressure network the pilot pressure already exists and only has to be tapped. This version does exactly that, returns pilot oil internally and sets 325 l/min nominal flow at 350 bar with spool symbol W6.

Benefits

• External pilot inlet uses the pilot pressure network that the plant already has.
• Internal return saves the second control line on the manifold.
• 325 l/min nominal flow and up to 870 l/min maximum flow.
• ±10 V voltage command handled by on-board electronics at the valve.
• 350 bar operating pressure, NBR seals, HL hydraulic fluid.

Applications

This combination is found on press lines, foundry equipment and large test fields where several valves are fed from one shared pilot supply. Mounting uses the standard size 25 pattern ISO 4401-08-08-0-05. The weight is 20.2 kg.
