Proportional Directional Valve 4WRZE25W8-325-7X/6EG24EK31/A1M - Bosch Rexroth R900974757

The larger the flow, the more the back pressure in the return matters. The 4WRZE25W8-325-7X/6EG24EK31/A1M answers that with an external pilot oil return and internal pick-up, converting 325 l/min nominal flow at a weight of 20.2 kg.

Benefits

• 325 l/min nominal flow, 870 l/min maximum flow
• External pilot oil return, independent of back pressure in the main return
• Internal pilot oil supply, so no additional pressure line is needed
• Spool symbol W8, three switching positions, four ports
• Analogue command value ±10 V, on-board electronics, 24 VDC supply
• Operating pressure up to 350 bar, subplate mounting ISO 4401-08-08-0-05

Application

A fit for fast press and forming axes whose return runs through a cooler and filter. Test benches with high piston speeds are another typical field. The NBR seals are designed for hydraulic fluid HL.
