Proportional Directional Valve 4WRLE25V400L-4X/MPY/24A1 - Bosch Rexroth R901466480

Large flow rates are metered steplessly straight from the machine controller, with no intermediate stage in the cabinet. The spool with symbol V is held by an internal position transducer, works on the ISO 4401-08-08-0-05 hole pattern of size 25 and releases 400 l/min nominal flow, up to 1250 l/min at 350 bar operating pressure.

Benefits

• Command value ±10 V fed directly to the on-board electronics, no external amplifier needed.
• 400 l/min nominal flow and 1250 l/min maximum flow on the size 25 hole pattern.
• Internal position transducer on the main spool, symbol V with 3 switching positions and 4 ports.
• Internal pilot oil supply with external pilot oil return through a dedicated Y line.
• NBR seals for hydraulic fluid HL, 19.36 kg weight, 350 bar maximum operating pressure.
• CE conformity, 24 V DC supply through a connector, 7-pole (6 + PE) according to EN 175201-804.

Applications

The valve is intended for axes with a high oil demand, for example presses, forging lines, test rigs and forming equipment. Combining size 25 with 400 l/min nominal flow keeps the manifold compact even though large cylinders are being served. The external pilot oil return calls for a Y line at the mounting point, while pilot oil is taken internally. NBR seals and hydraulic fluid HL define the permitted media.
