Proportional Directional Valve 4WRZ16E1-180-7X/6EG24N9EK4/D3M - Bosch Rexroth R901424365

The spool symbol decides how the axis behaves in centre position. The 4WRZ16E1-180-7X/6EG24N9EK4/D3M carries symbol E1 for that, meters 180 l/min nominal flow and takes its pilot oil internally.

Benefits

• Spool symbol E1 with 3 switching positions and 4 ports.
• 180 l/min nominal flow, 460 l/min maximum flow.
• Internal pilot oil supply, external pilot oil return to tank.
• Operating pressure up to 350 bar at a mass of 11.94 kg.
• Driven by external electronics, solenoid supply 24 V DC.
• Mounting pattern ISO 4401-07-07-0-05, NBR seals for HL hydraulic fluid.

Applications

The valve serves axes that need a defined connection of the actuator ports in centre position, for instance on lifting gear and winding drives. External drain keeps tank back pressure away from the pilot stage. NBR seals are fitted for mineral oil of class HL.
