Proportional Directional Valve 4WRZ16W8-180-7X/6EG24N9TK4/D3M - Bosch Rexroth R901456176

Fast rapid strokes call for more oil than a small nominal stage releases. The 4WRZ16W8-180-7X/6EG24N9TK4/D3M is therefore rated at 180 l/min nominal flow and allows a maximum of 460 l/min.

Benefits

• 180 l/min nominal flow, 460 l/min maximum flow.
• Operating pressure up to 350 bar at a mass of 11.8 kg.
• 3 switching positions to spool symbol W8, 4 ports.
• External pilot oil supply with internal pilot oil return.
• 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 serves axes with long rapid strokes, such as clamping units on injection moulding machines or lifting gear on test rigs. The upstream pressure reducing valve keeps the pilot stage steady even when system pressure fluctuates. NBR seals are fitted for mineral oil of class HL.
