Proportional Directional Valve 4WRTE25V350P-4X/6EG24EK31/F1M - Bosch Rexroth R901268849

Symmetrical cylinders with a heavy oil demand need a valve that meters large flow finely. The 4WRTE25V350P-4X/6EG24EK31/F1M brings 350 l/min nominal flow at 350 bar for exactly that and is driven by a 4 ... 20 mA current signal.

Benefits

• 350 l/min nominal flow at a valve mass of only 17.9 kg, a high power density per subplate.
• Spool symbol V keeps slow speeds steady through its fine metering edge, even though the valve is built for large flow.
• The 4 ... 20 mA current command is immune to voltage drop over long cables.
• Internal pilot oil supply and external pilot oil return tolerate raised tank back pressure without affecting pilot control.
• Maximum flow 870 l/min, mounting pattern ISO 4401-08-08-0-05.

Applications

Hydraulic presses, rolling mill stands and large clamping cylinders where rapid traverse and creep feed come from the same valve. The 24 VDC supply and 7-pole connector (6 + PE) are industry standard. On retrofits the valve drops onto existing size 25 subplates.
