Proportional Directional Valve 4WRLF16W8-200LJ-4X/MPY00/24ND90 - Bosch Rexroth R901536747

Not every system has a dedicated pilot circuit. The pilot-operated proportional directional valve 4WRLF16W8-200LJ therefore works with internal pilot oil supply and external pilot oil return, controlling 250 l/min nominal flow at 280 bar operating pressure through the integrated fieldbus electronics on the body.

Key benefits

• Internal pilot oil supply saves the separate pilot line, while the return stays external and can be routed without back pressure.
• 280 bar operating pressure covers standard size 16 circuits.
• 800 l/min peak flow leaves headroom above the 250 l/min nominal rating.
• Spool position feedback inside the valve gives accurate spool positioning without an external transducer.
• Fieldbus electronics with enable acknowledgment report the operating state back to the controller.
• 12 kg weight and connection diagram ISO 4401-07-07-0-05 for standard subplate mounting.

Applications

The type suits machine tools and handling systems in which a cylinder or hydraulic motor is accelerated and positioned steplessly. At a 280 bar design pressure there is enough margin to pressure peaks in a standard circuit. Internal pilot supply pays off wherever the main circuit already stays above the minimum pilot pressure and no extra pump is to be installed.
