Proportional Directional Valve 4WRLD25W8-350LJ-4X/MXT/24ND6T - Bosch Rexroth R901566378

When an axis brings its own control loop, computing time is left over in the controller. The 4WRLD25W8-350LJ-4X carries an integrated digital axis controller and meters 400 l/min nominal flow at up to 350 bar with it.

Benefits

• Integrated digital axis controller, position control runs inside the valve.
• Nominal flow of 400 l/min, maximum flow 1250 l/min in size 25.
• External pilot supply with internal return, only the X port is added.
• Voltage command ±10 V through a 12-pole (11 + PE) connector to EN 175201-804.
• Maximum operating pressure 350 bar, connection diagram ISO 4401-08-08-0-05.
• Mass of 19.72 kg, NBR seals, spool symbol W8.

Application

The valve drives controlled main axes on presses, testing machines and special purpose equipment. Its built-in controller saves a controller card and shortens commissioning. A dedicated line has to be run to the X port for the external pilot supply.
