Proportional Directional Valve 4WRKE32W6-600L-3X/6EG24K31/A1D3M - Bosch Rexroth R900780615

A dedicated pilot circuit pays off as soon as working pressure fluctuates while the pilot stage still needs a steady feed. The 4WRKE32W6-600L-3X/6EG24K31/A1D3M is built for that case: pilot oil arrives externally through X, the return leaves externally through Y, the main stage releases 600 l/min at up to 350 bar.

Benefits

• External pilot oil supply plus external pilot return keeps the pilot stage stable when working pressure swings.
• Spool symbol W6 relieves A and B to tank in centre position, so the cylinder rests free of force.
• 600 l/min rated flow, 1600 l/min maximum flow for the series.
• Analogue command value plus minus 10 V, 24 VDC supply, on-board electronics on the 7-pole connector (6 + PE).
• Mounting pattern ISO 4401-10-09-0-05, 4 ports, NBR seals, 37.04 kg.

Technical data

Applications

Applications are large power units with a separate pilot pump, for instance in forging presses, clamping systems and wind tunnel plants. The external Y port becomes mandatory once filters or coolers build back pressure in the tank line. With HL fluid and NBR seals the valve stays inside the usual mineral oil circuit.
