Proportional Directional Valve 4WRDE16W8-150L-6X/MPT/24A5 - Bosch Rexroth R901545039

Pilot oil supply and return run internally, so the subplate to ISO 4401-07-07-0-05 carries the four working ports and nothing else. The main spool is guided by internal position feedback and follows the ±10 V command value linearly, releasing 150 l/min nominal flow.

Benefits

• Internal position feedback of the main spool, linear relation between command value and flow.
• Nominal flow 150 l/min, maximum flow 460 l/min at 350 bar operating pressure.
• Internal pilot oil supply and return, which removes every extra pipe on the manifold.
• Spool symbol W8 with 3 switching positions and 4 ports.
• ±10 V command value on the on-board electronics, 24 VDC supply through a 7-pole (6 + PE) connector to EN 175201-804.
• NBR seals for HL hydraulic fluid, weight 10.5 kg.

Applications

The 4WRDE series works where position or speed of an axis has to follow a defined profile, for instance on test cylinders, feed drives and closed-loop axes in machine tools. Internal pilot oil routing shortens assembly, because the pilot stage is fed through the subplate. The ±10 V command value matches the analogue outputs of common controllers and control cards.
