Proportional Directional Valve 4WRZ25W8-325-7X/6EG24K4/M - Bosch Rexroth R900244923

Valve carriers bring pilot oil to every station through continuous channels. The 4WRZ25W8-325-7X/6EG24K4/M uses that gallery through external supply and external return and controls 325 l/min nominal flow.

Benefits

• External supply and return through the carrier channels, every valve hangs on the same feed.
• 325 l/min nominal flow, flow up to 870 l/min, spool symbol W8 in size 25.
• ISO 4401-08-08-0-05 pattern, four ports and three switching positions per station.
• 20.15 kg weight, 350 bar maximum operating pressure, NBR seals, HL hydraulic fluid.
• Commanded at 24 VDC through an external amplifier, 7-pole (6 + PE) plug to EN 175201-804.

Applications

Valve carriers appear in plants with many similar axes, for example on press lines and test fields. Because pilot pressure and filtration grade are the same for all stations, the axes behave uniformly. A single station can be swapped without interrupting the supply.
