Proportional Directional Valve 4WRDE16V1-150L-6X/MPT/24A5 - Bosch Rexroth R901539885

The 4WRDE16V1-150L-6X/MPT/24A5 needs neither an external X nor a Y line because pilot oil supply and pilot oil return are routed internally. For the machine builder that means a simpler manifold at 150 l/min nominal flow and 350 bar. Spool symbol V1 defines the control edges and the on-board electronics regulate the main spool through its position transducer.

Benefits

• Internal pilot oil supply and internal return, so no extra X or Y drilling in the manifold.
• Nominal flow 150 l/min with a maximum flow of 460 l/min.
• Operating pressure up to 350 bar with spool symbol V1 and three switching positions.
• Closed loop main spool with an analogue ±10 V command value.
• Valve weight 10.5 kg on an ISO 4401-07-07-0-05 mounting pattern.

Application

The variant fits standard power units in machine building where working pressure stays comfortably above pilot pressure. The NBR seals are rated for mineral oil HL. The electrical link is a 7-pole plug to EN 175201-804.
