Proportional Directional Valve 4WRZE10W8-85-7X/6EG24K31/F1M - Bosch Rexroth R901050470

Long signal runs and a varying system pressure often occur together, for example on widely spread power units. The 4WRZE10W8-85-7X/6EG24K31/F1M meets both with a 4 to 20 mA command value and external pilot routing, at 85 l/min nominal flow.

Benefits

• Command value 4 to 20 mA combined with external pilot oil supply and return.
• 85 l/min nominal flow in size 10, up to 170 l/min maximum.
• Spool symbol W8, three switching positions, four ports.
• 315 bar maximum operating pressure, connection diagram ISO 4401-05-05-0-05.
• 9.04 kg weight, on-board electronics at 24 V DC, UKCA to SI2016/1091.

Applications

The valve suits distributed plants with a central power unit and remote control blocks. Pilot pressure is fed there from a separate circuit and the signal stays stable despite the cable length. The intended hydraulic fluid is HL.
