Proportional Directional Valve 4WRZ10W8-50-7X/6EG24N9K4/M - Bosch Rexroth R900616671

Many axes fall exactly between the flow ratings. The 4WRZ10W8-50-7X/6EG24N9K4/M closes that gap with 50 l/min nominal flow on spool symbol W8 and still allows up to 170 l/min in the main channel.

Benefits

• 50 l/min nominal flow on spool symbol W8, the middle rating of this series in size 10.
• 3 switching positions and 4 ports on the ISO 4401-05-05-0-05 pattern.
• Pilot oil fed in and drained externally, pilot pressure and drain kept on separate paths.
• 315 bar operating pressure at 7.78 kg, NBR seals for HL hydraulic fluid.
• Concealed manual override, wired at 24 VDC through a 7-pole (6 + PE) plug to EN 175201-804.

Applications

The valve works on feed, infeed and clamping axes whose cylinders need moderate oil volumes. External pilot routing makes it possible to feed several valves in one manifold from a shared pilot supply. Since hole pattern and size stay the same within the series, the flow rating can be changed without reworking the subplate.
