Proportional Directional Valve 4WRZE10W6-50-7X/6EG24N9K31/A1D3V - Bosch Rexroth R900720440

This size 10 valve is the version with a fully external pilot oil circuit. Pilot inlet and outlet sit outside the main circuit, which gives the most uniform design in manifold solutions with a central pilot pump. Nominal flow is 50 l/min.

Benefits

• External pilot inlet and outlet suit manifolds with a central pilot pump
• 50 l/min nominal flow at 170 l/min maximum flow and 315 bar
• ±10 V command straight into the on-board electronics, without an intermediate amplifier
• Spool symbol W6, 3 switching positions, 4 ports, connection diagram ISO 4401-05-05-0-05
• FKM seals, HL hydraulic fluid, weight 8.48 kg

Applications

Multi-axis manifolds in machine tools and presses are the main case. A shared pilot supply keeps the response times of all axes alike. The electrical connection uses a 7-pole connector (6 + PE) to EN 175201-804.
