Proportional Directional Valve 4WRZE32W6-520-7X/6EG24N9K31/F1M - Bosch Rexroth R901026389

Next to frequency converters and contactors a voltage command has a hard time. The 4WRZE32W6-520-7X/6EG24N9K31/F1M therefore works from a 4...20 mA current command and meters 520 l/min at 350 bar, piloted externally through X and Y.

Benefits

• 4...20 mA current command instead of voltage, the signal stays clear in electrically noisy surroundings.
• 520 l/min at 350 bar, the size 32 body permits up to 1600 l/min.
• External pilot oil supply and external drain for load peaks with brief pressure collapse.
• W6 spool, four ports, three switching positions, ISO 4401-10-09-0-05.
• 43.44 kg, 24 V DC supply, NBR seals, HL hydraulic fluid, UKCA conformity.

Applications

The valve suits scrap shears, baling presses and briquetting plants with frequent switching. An external pilot circuit keeps the axis controllable during load peaks. Up to 1600 l/min stays in reserve if the plant is later run faster.
