Proportional Directional Valve 4WRLE27W6-430LJ-4X/MXY/24A1 - Bosch Rexroth R901404338

A dedicated pilot circuit can be filtered separately as well as set to its own pressure. This NG27 version takes pilot oil from outside plus discharges it outside, metering 430 l/min of nominal flow with spool symbol W6 while allowing peaks to 1850 l/min.

Benefits

• External pilot oil supply with external return allow separate pilot pressure plus separate filtration
• Spool symbol W6 blocks in mid position, which suits axes holding a standing load
• Nominal flow of 430 l/min, maximum flow 1850 l/min, operating pressure to 270 bar
• A ±10 V command value at on-board electronics with internal spool position feedback
• Connection diagram ISO 4401-08-07-0-05, NBR seals, CE conformity, mass 20.8 kg

Application

A match for control manifolds on presses plus forming plants that already carry a pilot circuit. Separate routing keeps pilot pressure steady through pressure drops in the main circuit. Exchange against other NG27 valves stays possible thanks to the standard connection diagram.
