Proportional Directional Valve 4WRLD25V400L-4X/MPT/24ND6T - Bosch Rexroth R901491981

A position-controlled axis with a large flow rate needs a controller right at the valve. The 4WRLD25V400L-4X/MPT/24ND6T has an integrated digital axis controller, delivers 400 l/min nominal flow at 280 bar operating pressure and weighs 18.58 kg.

Advantages

• Integrated digital axis controller processes the ±10 V command value directly in the valve.
• 400 l/min nominal flow at 280 bar operating pressure, maximum flow 1250 l/min.
• Internal pilot oil supply and internal return without extra pilot lines.
• Spool symbol V with 3 switching positions across 4 ports.
• Connector 12-pole (11 + PE) according to EN 175201-804 for extended controller communication.
• 18.58 kg weight on connection diagram ISO 4401-08-08-0-05, NBR seals for hydraulic fluid HL.

Applications

The integrated digital axis controller suits position-controlled motion on large cylinders, for example in presses or test benches with a high flow demand. Spool symbol V with 3 switching positions covers extend, block and retract in a single valve. The internal pilot oil routing reduces external piping at the axis.
