Proportional Directional Valve 4WRZE10W8-50-7X/6EG24K31/A1V - Bosch Rexroth R900976964

A central pilot supply holds pilot pressure steady even when working pressure collapses. This version makes use of that through external supply and external drain, controlling 50 l/min nominal flow at 315 bar.

Benefits

• External pilot oil supply and external pilot oil drain, keeping pilot pressure independent of working pressure at the 315 bar system rating.
• 50 l/min nominal flow, up to 170 l/min maximum flow.
• No built-in pressure reducing valve, matched to an already regulated pilot circuit.
• FKM seals, ±10 V command value, 24 V DC supply through a 7-pole connector (6 + PE).
• 8.48 kg weight, spool symbol W8, ISO 4401-05-05-0-05 interface.

Applications

Common on multi-axis manifolds served by a separate pilot power unit. The pilot stage stays supplied even when working pressure swings hard. 50 l/min matches a mid range axis in size 10.
