Proportional Directional Valve 4WRKE27R3-500L-3X/6EG24TK31/A1D3M - Bosch Rexroth R901099052

When several consumers share one tank gallery, the pressure there is rarely calm. The 4WRKE27R3-500L-3X/6EG24TK31/A1D3M routes its pilot oil drain externally for that reason and keeps the pilot stage clear of those fluctuations, at 500 l/min nominal flow and 270 bar operating pressure.

Benefits

• External pilot oil drain in the TK31 version decouples the pilot stage from return line pressure.
• 500 l/min nominal flow and up to 1000 l/min maximum flow in size 27.
• A ±10 V command value, on-board electronics, 24 VDC supply.
• Spool symbol R3 with three switching positions across four ports, ISO 4401-08-08-0-05 mounting pattern.
• Operating pressure up to 270 bar, 19.68 kg valve mass, NBR seals for HL hydraulic fluid.

Application

A fit for manifolds where several large valves share the same return, for example in press lines and test rigs. The external pilot drain needs its own line to tank. Mounting pattern and size match the other versions of the series.
