Proportional Directional Valve 4WRZE32W6-360-7X/6EG24N9K31/F1D3V - Bosch Rexroth R901341891

Machines with their own pilot pump want a main stage that uses that circuit instead of building a second one. This size 32 version therefore runs external pilot oil supply and external pilot oil return. It sets 360 l/min nominal flow, tolerates up to 1600 l/min and operates to 350 bar, with a 4 to 20 mA current command.

Key benefits

• External pilot oil supply and external pilot oil return hold pilot pressure steady even when working pressure drops during the cycle
• 360 l/min nominal flow in size 32, ceiling 1600 l/min
• 350 bar operating pressure, connection diagram ISO 4401-10-09-0-05
• 4 to 20 mA command value, on-board electronics on 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804
• Spool symbol W6 with 3 switching positions and 4 ports
• 44 kg weight, FKM seals, HL hydraulic fluid

Applications

An external pilot circuit earns its lines when working pressure falls below the pilot pressure the main spool needs, for instance during the rapid stroke of a press or while an accumulator unloads. Spool travel stays repeatable across such cycles. The 360 l/min rating covers medium to large cylinders.
