Proportional Directional Valve 4WRZ16W8-180-7X/6EG24N9K4/D3M - Bosch Rexroth R901415055

A separate pilot circuit lets the proportional valve keep metering even when system pressure collapses for a moment. The 4WRZ16W8-180-7X/6EG24N9K4/D3M is therefore supplied and drained externally, at 180 l/min nominal flow.

Benefits

• External pilot oil supply and external pilot oil return, metering stays independent of working pressure.
• 180 l/min nominal flow, 460 l/min maximum flow.
• Operating pressure up to 350 bar at a mass of 11 kg.
• 3 switching positions to spool symbol W8, 4 ports.
• Driven by external electronics, connector 7-pole (6 + PE) to EN 175201-804.
• Mounting pattern ISO 4401-07-07-0-05, NBR seals for HL hydraulic fluid.

Applications

The valve works in systems with their own pilot pump, for example presses with deep pressure dips on reversal or test rigs under changing load. Concealed auxiliary actuation allows the axis to be moved during commissioning. NBR seals are fitted for mineral oil of class HL.
