Proportional Directional Valve 4WRKE10E25L-3X/6EG24TK31/A1D3M - Bosch Rexroth R901223157

A positioning axis is only as accurate as the spool that reproduces the command. The 4WRKE10E25L-3X/6EG24TK31/A1D3M measures its spool position internally and feeds it back, working with 25 l/min nominal flow and the command value ±10 V.

Benefits

• 25 l/min nominal flow in size 10, throughput up to 150 l/min.
• Spool symbol E, three switching positions across four ports.
• Command value ±10 V at the on-board electronics, 24 VDC supply.
• Pilot oil supplied externally and returned internally, as supplied and fixed in the type code.
• 315 bar maximum operating pressure on connection diagram ISO 4401-05-05-0-05.
• 8.39 kg, NBR seals, 7-pole connector (6 + PE) to EN 175201-804.

Technical data

Applications

The usual case is a controlled axis on machinery running HL hydraulic fluid at up to 315 bar operating pressure. Maintenance departments also fit it when an existing axis is converted to closed-loop control with on-board electronics.
