Proportional Directional Valve 4WRLD25E1-400LJ-4X/MXY/24ND6T - Bosch Rexroth R901561401

At 18.5 kg the 4WRLD25E1-400LJ-4X/MXY/24ND6T is one of the lighter valves in its frame size and still covers 400 l/min nominal flow at 350 bar operating pressure. Spool symbol E1 controls 4 ports across 3 switching positions, with pilot oil supplied and returned externally.

Key benefits

• Spool symbol E1 with 3 switching positions and 4 ports in size 25.
• 400 l/min nominal flow and up to 1250 l/min maximum flow.
• 350 bar operating pressure for main drives under high load.
• 18.5 kg installed weight makes mounting and replacement easier on manifolds with poor access.
• Integrated digital axis controller, ±10 V command value, 12-pole connector (11 + PE) to EN 175201-804.
• External pilot oil supply and external pilot oil return at 24 VDC supply voltage.

Applications

Typical installations are position-controlled axes in presses, test rigs and special purpose machines that require a rest position to symbol E1. External pilot routing allows a dedicated feed for the pilot stage. The subplate pattern to ISO 4401-08-08-0-05 is interchangeable with the other size 25 valves.
