Proportional Directional Valve 4WRKE32E600L-3X/6EG24EK31/A1D3M - Bosch Rexroth R901033473

On large cylinders the cycle time depends on how much oil the main stage releases. The 4WRKE32E600L-3X/6EG24EK31/A1D3M releases 600 l/min rated flow at up to 350 bar, takes its pilot oil internally from the P channel and routes the pilot return separately to the outside.

Benefits

• 600 l/min rated flow in size 32, the series carries up to 1600 l/min maximum flow.
• Internal pilot oil supply saves a dedicated pilot pump, the external pilot return stays independent of tank pressure in the main stage.
• Spool symbol E with 3 switching positions keeps the centre position blocked while A and B are relieved at zero.
• Command value plus minus 10 V via on-board electronics, 24 VDC supply on the 7-pole connector (6 + PE) to EN 175201-804.
• Mounting pattern ISO 4401-10-09-0-05, NBR seals for HL fluid, 35.8 kg.

Applications

Typical duties are main drives of hydraulic presses, lifting gear in steel construction and test rigs with large differential cylinders. Internal pilot supply is sufficient as long as the P port always carries at least the pilot pressure. The separate return helps where the tank line carries back pressure from other consumers.
