Proportional Directional Valve 4WRTE10W8-50L-4X/6EG24K31/A1V - Bosch Rexroth R901186584

Where the controller provides voltage outputs, a valve with a plus or minus 10 V input saves a signal converter. The 4WRTE10W8-50L-4X/6EG24K31/A1V processes the voltage command directly, meters 50 l/min nominal flow on a linear curve and draws its control oil externally, at operating pressures up to 350 bar.

Benefits

• 50 l/min nominal flow with spool symbol W8, 4 ports and 3 switching positions.
• External pilot oil supply and external pilot oil return separate the pilot circuit from the main circuit.
• An internal position transducer reports spool position to the control loop, and the characteristic curve is linear. Operating pressure reaches 350 bar.
• The ±10 V command value feeds the on-board electronics directly, supplied with 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• Hole pattern ISO 4401-05-05-0-05 to ISO 4401, FKM seals for HL fluid, 170 l/min maximum flow at 8.49 kg.

Applications

The variant fits test rigs and special machines whose control cards output voltage signals. FKM seals allow higher oil temperatures, for example in continuous duty with a cooling circuit. Internal spool feedback holds position through load changes.
