Proportional Directional Valve 4WRZ25W6-325-7X/6EG24EK4/D3M - Bosch Rexroth R900738166

The step from 220 to 325 l/min decides how fast a cylinder extends. The 4WRZ25W6-325-7X/6EG24EK4/D3M is the faster build of the same size 25: 325 l/min nominal flow, peaks up to 870 l/min, pilot oil supplied internally and drained externally.

Benefits

• 325 l/min nominal flow on the same ISO 4401-08-08-0-05 pattern as the smaller ratings of the series.
• Up to 870 l/min flow and 350 bar operating pressure as the upper limits of the valve.
• Pilot oil supplied internally, drained externally through a dedicated drain line.
• Spool symbol W6, 20.42 kg weight, three switching positions across four ports.
• NBR seals, HL hydraulic fluid, 24 VDC through a 7-pole (6 + PE) plug to EN 175201-804.

Applications

The valve is intended for main axes on presses, shears and stretching lines with large cylinder volumes. The higher nominal flow shortens rapid traverse times without any change to the subplate. As a spare part it fits wherever a 4WRZ(E) valve in size 25 is already installed.
