Proportional Directional Valve 4WRZE10W6-50-7X/6EG24N9K31/A1D3M - Bosch Rexroth R900763192

In systems with a dedicated pilot pump the pilot stage should stay independent of working pressure. The 4WRZE10W6-50-7X/6EG24N9K31/A1D3M is therefore supplied and drained externally, metering 50 l/min nominal flow with spool symbol W6 at operating pressures up to 315 bar.

Benefits

• 50 l/min nominal flow with spool symbol W6, 4 ports and 3 switching positions.
• External pilot oil supply and external pilot oil return separate the pilot circuit from the main circuit.
• A pressure reducing valve in the pilot stage caps control pressure, working pressure may reach 315 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, NBR seals for HL fluid, 170 l/min maximum flow at 8.42 kg.
• UKCA conformity to SI2016/1091 covering electromagnetic compatibility.

Applications

The variant earns its place wherever working pressure swings widely or drops below the pilot pressure needed, for example on accumulator duty or constant pressure control. The 50 l/min suit medium feed axes on machine tools and test rigs. X and Y lines have to be provided in the subplate.
