Proportional Directional Valve 4WRLD10V1-100L-4X/MPT/24ND6T - Bosch Rexroth R901491897

A differential cylinder travels at unequal speeds in both directions once the valve opens symmetrically. The 4WRLD10V1-100L-4X/MPT/24ND6T therefore relies on spool symbol V1, feeds its pilot stage internally, plus holds 280 bar operating pressure at 9.12 kg.

Key benefits

• Spool symbol V1 matched to cylinders whose piston areas differ between both sides.
• Internal pilot oil supply with internal return simplifies the subplate layout.
• Nominal flow of 100 l/min, peak flow of 300 l/min, operating pressure of 280 bar.
• Integrated digital axis controller, command value plus or minus 10 V, supply 24 VDC.
• Mass of 9.12 kg, interface ISO 4401-05-05-0-05, NBR seals for HL mineral oil.

Applications

Typical duties are lifting cylinders, tilting axes plus press rams whose piston area differs widely from the annulus area. The internal pilot circuit assumes sufficient system pressure, otherwise the pilot stage switches too slowly. Connection is 12-pole to EN 175201-804.

Manufacturer

Bosch Rexroth supplies the valve as 4WRLD10V1-100L-4X/MPT/24ND6T under material number R901491897. The digit 1 behind the V marks the spool variant plus must be observed on any replacement.
