Proportional Directional Valve 4WRLE16E250LJ-4X/VPT/24A1 - Bosch Rexroth R901503382

Where a hydraulic circuit is built without a separate pilot supply, the pilot circuit variant decides how much piping is needed. This version of the size 16 range feeds itself internally and returns pilot oil internally, at 250 l/min nominal flow and operating pressure up to 350 bar.

Benefits

• Internal pilot oil supply plus internal return save two lines, the manifold pattern stays at ISO 4401-07-07-0-05.
• 250 l/min nominal flow, the range itself carries up to 800 l/min maximum flow.
• Control electronics sit on the valve body, processing ±10 V from a 24 VDC supply.
• Spool symbol E with 3 switching positions across 4 ports covers standard axes that need a mid position.
• FKM seals at a mass of 11.72 kg, hydraulic fluid class HL.

Applications

The variant fits compact power units in machine building, clamping axes and conversions where no separate pilot line is available. An internal return requires a tank port with low enough back pressure. Inside that limit the axis runs up to 350 bar.

Manufacturer

Bosch Rexroth, material number R901503382. The type code 4WRLE16E250LJ-4X/VPT/24A1 differs from the X variants exactly in how pilot oil is routed. Conformity CE.
