Proportional Directional Valve 4WRLE25W6-350LJ-4X/MPY/24L1 - Bosch Rexroth R901580612

An analogue card per axis costs cabinet space plus a screened cable. The 4WRLE25W6-350LJ-4X/MPY/24L1 is driven over IO-Link instead, meters 350 l/min rated flow at up to 350 bar, reports spool position internally.

Benefits

• IO-Link replaces the analogue signal, command value plus diagnostics run digitally over the 5-pole M12 connector, coding A.
• 350 l/min rated flow in size 25, the series takes up to 1250 l/min maximum flow.
• Internal pilot oil supply with external pilot return keeps the pilot stage free of tank pressure.
• Internal spool position feedback with a linear characteristic, spool symbol W6, 3 switching positions, 4 ports.
• CE conformity, 24 V DC, mounting pattern ISO 4401-08-08-0-05, NBR seals, 18.5 kg.

Applications

The valve belongs on axes tied into a networked machine control, on presses, injection moulding machines, test rigs with central diagnostics. IO-Link allows parameters to be read out, then written back per device during service. Internal pilot intake assumes that the P port always carries pilot pressure.
