Proportional Directional Valve 4WRZE10W9-50-7X/6EG24ETK31/F1D3M - Bosch Rexroth R901081368

The fewer pilot lines a manifold needs, the smaller it turns out. This 4WRZE10W9-50-7X routes pilot supply and return entirely inside, so four working ports are enough, at 50 l/min nominal flow and up to 315 bar.

Benefits

• Internal pilot oil routing in both directions, so no extra drillings in the manifold.
• A 4...20 mA command and 24 VDC supply share one 7-pole connector (6 + PE) to EN 175201-804.
• The built-in pressure reducing valve secures pilot pressure at working pressures to 315 bar.
• 50 l/min nominal flow in size 10, mounting pattern ISO 4401-05-05-0-05, weight 8.48 kg.

Applications

The valve prefers compact manifold blocks in machine tools and test equipment. Three switching positions and spool symbol W9 cover extending, holding and relieving a cylinder. NBR seals are rated for mineral oil of class HL.
