Proportional Directional Valve 4WRZ10W9-50-7X/6EG24N9K4/M - Bosch Rexroth R901088128

In larger manifolds one pilot pressure pump supplies several proportional valves at once. The 4WRZ10W9-50-7X/6EG24N9K4/M is designed for that, works without a pressure reducing valve of its own and controls 50 l/min nominal flow.

Benefits

• External pilot oil supply and external return, connection to a shared pilot pressure circuit.
• Without a pressure reducing valve in the pilot stage, regulation sits centrally in the circuit.
• 50 l/min nominal flow, up to 170 l/min flow at 315 bar.
• Spool symbol W9 with 3 switching positions across 4 ports in size 10.
• 8.24 kg, 24 VDC, NBR seals, 7-pole plug (6 + PE) to EN 175201-804.

Applications

It is intended for manifolds with several controlled axes and a shared pilot pressure supply. Central regulation saves one reducing valve per valve and unifies the pilot pressure. The middle nominal step suits axes with changing speed.
