Proportional Directional Valve 4WRLD16V250L-4X/MPY/24ND6T - Bosch Rexroth R901505815

Building a controlled axis without a separate pilot pump saves a whole line and one source of faults. The 4WRLD16V250L-4X/MPY/24ND6T feeds its pilot stage internally while delivering 250 l/min nominal flow at 280 bar operating pressure.

Benefits

• Internal pilot oil supply with external pilot oil return, one pilot line fewer in the power unit.
• 280 bar operating pressure and 250 l/min nominal flow, up to 800 l/min maximum.
• Spool symbol V with three switching positions and internal spool position feedback.
• Integrated digital axis controller with analog command value plus/minus 10 V from a 24 VDC supply.
• Weight 12.66 kg in size 16 with mounting pattern ISO 4401-07-07-0-05.

Applications

The valve is intended for controlled axes at medium pressure level, for example in handling and testing systems whose power unit works up to 280 bar. Internal pilot supply requires sufficient pressure in the main line. NBR seals are matched to hydraulic fluid HL.
