Proportional Directional Valve 4WRKE25W8-220L-3X/6EG24EK31/F1D3V - Bosch Rexroth R901532515

A 4...20 mA current signal stays immune to interference over longer cable runs. The 4WRKE25W8-220L-3X/6EG24EK31/F1D3V accepts exactly that signal and turns it into up to 220 l/min nominal flow, with internal spool position feedback.

Benefits

• 4...20 mA command value at the on-board electronics with 24 VDC supply, wired through a connector, 7-pole (6 + PE) according to EN 175201-804.
• Internal spool position feedback and a linear characteristic curve for even actuating behaviour.
• 220 l/min nominal flow and flow up to 870 l/min at a maximum operating pressure of 350 bar.
• Internal pilot oil supply with external pilot oil return, so the pilot return line can be routed without back pressure.
• FKM seals for HL hydraulic fluid, three switching positions with spool symbol W8 across four ports.

Technical data

Applications

On the ISO 4401-08-08-0-05 hole pattern the valve replaces an existing size 25 unit in presses, hydraulic power units and test benches. The current command value suits control cabinets placed further away, because voltage drop along the cable does not distort the signal. Spool symbol W8 and 220 l/min nominal flow move cylinders continuously in both directions.
