Proportional Directional Valve 4WRZ10W8-50-7X/6EG24N9K4/D3M - Bosch Rexroth R900732469

Anyone running an accumulator has phases without pump pressure. The 4WRZ10W8-50-7X/6EG24N9K4/D3M therefore draws its pilot oil from a dedicated source and stays controllable throughout at 50 l/min nominal flow.

Benefits

• External pilot oil supply and external return, controllable even with an unloaded main circuit.
• 50 l/min nominal flow, up to 170 l/min flow at 315 bar.
• Spool symbol W8 with 3 switching positions, 4 ports to ISO 4401-05-05-0-05.
• Pressure reducing valve in the pilot stage and concealed auxiliary actuation.
• 8.28 kg, 24 VDC, external electronics, NBR seals for HL hydraulic fluid.

Applications

This variant belongs in the accumulator circuit of presses and clamping systems with idle circulation. Pilot oil comes from the accumulator or an auxiliary pump and keeps the pilot stage working. The middle nominal step covers feed and rapid traverse alike.
