Proportional Directional Valve 4WRGE25V1-350P-1X/315G24ETK31/A1WC152M - Bosch Rexroth R901324576

Retrofits usually fail on the pilot circuit piping rather than on the valve itself. The 4WRGE25V1-350P-1X/315G24ETK31/A1WC152M draws its pilot oil internally and returns it the same way, at 350 l/min nominal flow and 350 bar.

Benefits

• Internal pilot oil supply with internal return removes the need for extra pilot lines.
• 350 l/min nominal flow in size 25, peaking at a maximum flow of 870 l/min.
• Symbol V1 with 3 switching positions across 4 ports, pilot-operated design with spool position control.
• ±10 V command value into the on-board electronics, 24 VDC supply, 7-pole connector (6 + PE).
• 18.46 kg weight with subplate mounting to ISO 4401-08-08-0-05, NBR seals.

Technical data

Application

The design fits power units where the pilot circuit cannot be routed separately, such as compact manifold stations. At 350 l/min it serves cylinders with large swept volume without giving up accuracy in slow motion. HL hydraulic fluid with NBR seals matches a standard mineral oil installation.

Manufacturer

Bosch Rexroth, material number R901324576, product family 4WRGE10,16,25. Internal piloting assumes a sufficiently high system pressure at port P.
