Proportional Directional Valve 4WRKE35W6-1000L-3X/6EG24EK31/F1D3M - Bosch Rexroth R901263621

Pilot oil routing decides how much pipework a manifold needs. The 4WRKE35W6-1000L-3X/6EG24EK31/F1D3M takes pilot pressure internally from the main circuit and returns it externally, which decouples the pilot return from back pressure in the main line. Flow is 1000 l/min nominal and up to 3000 l/min maximum at 350 bar.

Benefits

• Internal pilot oil supply, external pilot oil return, no separate pilot pump required.
• 1000 l/min nominal flow, up to 3000 l/min maximum, at 350 bar operating pressure.
• Spool symbol W6 with a linear characteristic curve and internal spool position feedback.
• Connection diagram ISO 4401-10-09-0-05, three switching positions across four ports, 69 kg.
• Command value 4...20 mA through on-board electronics, 24 VDC supply, 7-pole connector (6 + PE) to EN 175201-804.

Applications

The valve fits large cylinders in presses, injection moulding machines and test rigs whose main circuit carries enough pressure for internal piloting. External pilot return is chosen where the shared tank gallery builds back pressure under load. Plan the separate pilot return line when laying out the manifold.
