Proportional Directional Valve 4WRZE25E220-7X/6EG24N9EK31/A1M - Bosch Rexroth R901033631

Not every controller has a current output to spare, while a ±10 V voltage output is nearly always available. This version of the 4WRZE25 takes exactly that signal and turns it into 220 l/min nominal flow at 350 bar, with spool symbol E and internal pilot supply.

Benefits

• ±10 V voltage command without an extra converter card in the control cabinet.
• 220 l/min nominal flow for medium axes, up to 870 l/min at peak.
• 350 bar operating pressure on a valve that fits the ISO 4401-08-08-0-05 pattern.
• Internal pilot supply and external pilot return keep the pilot stage clear of tank back pressure.
• On-board electronics with a 7-pole connector (6 + PE), 24 VDC supply.

Applications

The valve is intended for feed and positioning axes in presses, machine tools and test equipment. Because the electronics are inside the valve, no free slot has to be found in the cabinet. The operating medium is HL hydraulic fluid, sealed with NBR.
