Proportional Directional Valve 4WRPEH6C4B40L-3X/V/24C6 - Bosch Rexroth R901505315

If the command signal fails, the axis should not stop at random. The 4WRPEH6C4B40L-3X/V/24C6 therefore carries a safety shut-down with an additional fail-safe position, works with 40 l/min nominal flow and spool symbol C4.

Benefits

• 40 l/min nominal flow in size 6, throughput up to 50 l/min.
• Spool symbol C4, four switching positions across four ports.
• Command value ±10 ma at the on-board electronics, 24 VDC supply.
• 350 bar maximum operating pressure on connection diagram ISO 4401-03-02-0-05.
• Safety shut-down with an additional fail-safe position for a defined rest position of the axis.
• 3 kg, FKM seals, 7-pole connector (6 + PE), direct actuated.

Applications

It runs in systems with HL hydraulic fluid at up to 350 bar operating pressure, for example on clamping fixtures, infeed axes and test equipment. The safety requirement placed on the rest position decides which spool version is chosen.
