Proportional Directional Valve 4WRKE35E1000P-3X/6EG24K31/F1D3M - Bosch Rexroth R901168827

Large hydraulic axes need volume and fine metering at the same time. This size 35 proportional directional valve of the 4WRKE series meters 1000 l/min nominal flow, passes up to 3000 l/min at peak and works at operating pressures up to 350 bar. Internal spool position feedback holds the commanded opening even when the load changes.

Benefits

• 1000 l/min nominal and up to 3000 l/min maximum flow feed large cylinders without paralleling several valves.
• Operating pressure up to 350 bar, rated for HL hydraulic fluid.
• Internal spool position feedback and a linear characteristic curve with a fine control range give repeatable motion profiles.
• The 4 to 20 mA command input stays accurate over long cable runs between cabinet and manifold.
• ISO 4401-10-09-0-05 connection pattern fits any standard subplate of this size.
• On-board electronics on 24 VDC with a 7-pole (6 + PE) connector to EN 175201-804 remove the need for a separate amplifier card.

Applications

It belongs in presses, rolling mills, forging lines and large test rigs where a cylinder has to be moved under position control at high flow. Pilot oil is supplied and returned externally, so the machine needs its own pilot circuit. At 69.6 kg the valve is mounted on a fixed control manifold rather than on a moving assembly.
