Proportional Directional Valve 4WRKE32W8-600L-3X/6EG24K31/F1D3V - Bosch Rexroth R901270327

When system pressure collapses during a load change, an internally piloted axis loses dynamics. The 4WRKE32W8-600L-3X/6EG24K31/F1D3V therefore draws pilot oil from outside and holds 600 l/min nominal flow at 350 bar.

Benefits

• Fully external pilot routing, keeping the pilot stage steady through pressure dips in the main circuit.
• 600 l/min nominal flow in size 32, with a 1600 l/min peak.
• Command value 4 to 20 mA, resistant to interference on long signal lines.
• Symbol W8 with a linear characteristic curve and three switching positions at 350 bar.
• 37.2 kg weight, FKM seals, HL hydraulic fluid, 24 VDC supply.

Application

The version suits presses and forming lines whose system pressure varies strongly through the cycle. A dedicated pilot circuit holds control pressure constant and keeps stroke times reproducible. On plants without a separate pilot source, the internally fed variant of the same range is the simpler answer.
