Proportional Directional Valve 4WRLD25V1-400L-4X/MPT/24ND6T - Bosch Rexroth R901519584

Where the hydraulic diagram has no dedicated control pressure line, the internal pilot oil supply of the MPT version saves the entire additional plumbing. The valve then runs 400 l/min nominal flow at 280 bar maximum operating pressure with spool symbol V1.

Key benefits

• Internal pilot oil supply and internal pilot oil return, no external control lines required.
• 400 l/min nominal flow in size 25, up to 1250 l/min maximum flow.
• 280 bar operating pressure, matched to circuits with internal pilot supply.
• Spool symbol V1 with 3 switching positions, 4 ports and internal spool position feedback.
• Integrated digital axis controller with ±10 V command value at 24 VDC supply voltage.
• 19.64 kg, subplate mounting to ISO 4401-08-08-0-05, 12-pole connector (11 + PE).

Applications

The version suits retrofits and compact power units with no room for extra control oil lines. In test rigs, lifting gear and clamping systems 280 bar is usually sufficient. HL is the intended hydraulic fluid, the seals are NBR.
