Proportional Directional Valve 4WRDE16V150L-6X/MXTWG/24A5 - Bosch Rexroth R901535483

Some power units run a pilot pump of their own yet provide no separate drain channel for the pilot circuit. For exactly that layout the 4WRDE16V150L-6X/MXTWG/24A5 draws pilot oil externally and discharges it internally while metering 150 l/min nominal flow at a maximum operating pressure of 350 bar.

Benefits

• 150 l/min nominal flow in size 16, maximum flow 460 l/min.
• External pilot oil supply with internal return, so the separate Y line is not required.
• Spool symbol V with 3 switching positions on 4 ports and internal spool position feedback.
• Maximum operating pressure 350 bar, mounting pattern ISO 4401-07-07-0-05, 10 kg installed weight.
• Command value ±10 V at 24 VDC, 7-pole connector (6 + PE) according to EN 175201-804, NBR seals for HL hydraulic fluid.

Technical data

Applications

The valve suits axes in presses and test rigs whose power unit has a pilot pump but no dedicated pilot drain channel in the manifold. An internal return simplifies the plumbing because one bore less is needed. With 150 l/min nominal flow and a 460 l/min flow limit there is room for fast approach movements.
