Proportional Directional Valve 4WRZ10W9-50-7X/6EG24N9ETK4/M - Bosch Rexroth R900249195

The middle nominal step meets the demand of many axes without filling the manifold with lines. The 4WRZ10W9-50-7X/6EG24N9ETK4/M controls 50 l/min nominal flow and feeds and discharges its pilot oil internally.

Benefits

• 50 l/min nominal flow, 170 l/min maximum flow at 315 bar operating pressure.
• Internal pilot oil supply and internal return, no additional lines in the manifold.
• Without a pressure reducing valve in the pilot stage, one part fewer in the pilot oil path.
• Spool symbol W9 with 3 switching positions across 4 ports in size 10.
• 8.24 kg, 24 VDC, external electronics, NBR seals for HL hydraulic fluid.

Applications

It is intended for medium feed and lifting axes in crowded manifolds. Internal pilot routing saves two ports per valve. The command value comes from an external amplifier card that finds room in the control cabinet.
