Proportional Directional Valve 4WRLE 16 E250LJ-4X/MPT/24C6 - Bosch Rexroth R901554663

Not every control card puts out a voltage, some work with a bipolar current of plus/minus 10 mA. This 4WRLE16E250LJ accepts exactly that signal and removes the need for a converter in between. It delivers 250 l/min nominal at an 800 l/min limit, controls the main spool through internal position feedback and routes pilot oil in and out internally.

Benefits

• Command value plus/minus 10 mA, matching controllers with a bipolar current output.
• 250 l/min nominal flow, limit 800 l/min at 350 bar.
• Internal main spool position feedback, linear characteristic with symbol E.
• Pilot oil in and out internally, no X and no Y line required.
• On-board electronics, 24 VDC supply, 7-pole connector to EN 175201-804.
• CE conformity, NBR seals for HL fluid, weight 11.9 kg.

Technical data

Applications

The valve replaces existing axis valves in plants whose control cards are built around a current command, with no change to the control system. Its high 250 l/min rating makes it usable on fast cylinder axes in presses and test rigs. Internal pilot routing requires a system pressure above the minimum pilot pressure.
