Proportional Directional Valve 4WRPEH6C3B25P-3X/M/24F1 - Bosch Rexroth R901382535

A proportional directional valve is only as good as the signal reaching it. This version works on a 4...20 mA current command value that stays immune over long cable runs, controlling 25 l/min nominal flow in size 6.

Advantages

• 25 l/min nominal flow, peaks up to 41 l/min at a maximum operating pressure of 350 bar.
• Command value 4...20 mA, the on-board electronics process the current signal directly at the valve.
• Spool symbol C3 in 4 switching positions, and the fail-safe position of the safety shut-down.
• Internal piston position feedback keeps the spool on the command value regardless of flow forces.
• 3 kg mass, ISO 4401-03-02-0-05 interface for subplate mounting on any standard plate.

Applications

Typical duties are axes on machine tools and plastics machinery whose controller sits in the cabinet several metres away. The fail-safe position supports emergency stop concepts that require a defined valve state once the electronics are switched off. As a spare it fits existing size 6 subplates.
