Proportional Directional Valve 4WRTE27E1-500L-4X/6EG24TK31/A1M - Bosch Rexroth R901427378

Internal spool position feedback turns the directional valve into a controlled axis: the analog command value ±10 V is converted into a spool position and held there. Size 27 provides 500 l/min nominal flow and a maximum flow of 1000 l/min for the job.

Benefits

• Internal spool position feedback for repeatable positioning, analog command value ±10 V
• 500 l/min nominal flow, maximum flow 1000 l/min, maximum operating pressure 270 bar
• Spool symbol E1 with 3 switching positions across 4 ports, linear characteristic
• Pilot oil supplied externally and returned internally, matching power units that run their own pilot pump
• On-board electronics on 24 VDC, NBR seals for HL hydraulic fluid, weight 19.32 kg

Applications

Presses, hoists and transfer axes whose control calls for a defined centre state at the actuator ports are the typical case. The external pilot supply secures switching even when working pressure drops for a moment. The valve sits on a subplate to ISO 4401-08-07-0-05, pilot oil returns internally.
