Proportional Directional Valve 4WRZE25W6-325-7X/6EG24TK31/A1D3M - Bosch Rexroth R901254925

Some plants have a pilot pump but no separate return line for the pilot stage. The 4WRZE25W6-325-7X/6EG24TK31/A1D3M fits exactly there, taking its feed from outside and returning internally to tank, at 325 l/min nominal flow and operating pressures up to 350 bar.

Benefits

• External pilot oil supply with internal return means only one extra line has to be laid.
• 325 l/min nominal flow with a symmetrical spool of symbol W6.
• A built-in pressure reducing valve holds pilot pressure constant when working pressure fluctuates.
• Plus or minus 10 V command into on-board electronics, 24 VDC at a 7-pole connector (6 + PE) to EN 175201-804.
• UKCA conformity to SI2016/1091, NBR seals, mounting pattern ISO 4401-08-08-0-05.

Applications

The valve works on rotary drives and through-rod cylinders in presses, rolling lines and hoists that already run a pilot pump. Because the pilot return is internal, the tank line should carry as little back pressure as possible. Range maximum flow amounts to 870 l/min.
