Proportional Directional Valve 4WRLE16W6-200LJ-4X/MPT/24L1 - Bosch Rexroth R901570922

A valve that is driven digitally and routes its own pilot oil gets by with one cable and four oil ports. That is how this 4WRLE16W6-200LJ is built, with IO-Link control on the 5-pole M12 connector and a pilot stage fed and relieved internally. Hydraulically it meters 200 l/min nominal at an 800 l/min limit and 350 bar.

Benefits

• IO-Link instead of an analogue signal, parameters and diagnostics share one line.
• Pilot oil in and out internally, only P, T, A and B are used at the subplate.
• 200 l/min nominal flow, limit 800 l/min at 350 bar.
• Internal main spool position feedback for load-independent metering.
• Connector M12 x 1 with A coding, 5-pole, 24 VDC supply.
• Valve weight 11.62 kg, port pattern ISO 4401-07-07-0-05.

Technical data

Applications

The combination suits modern machines where every field device hangs on an IO-Link master and parameters are maintained centrally. With no pilot lines to route, commissioning takes noticeably less time. For systems with high back pressure in the return, pick the externally drained version instead.
