Proportional Directional Valve 4WRLE16E250LJ-4X/MXY/D24A1 - Bosch Rexroth R901562713

In maintenance work the seal class of a replacement valve decides whether it can go in at all. This build of the size 16 range uses NBR seals, meters 250 l/min at operating pressure up to 350 bar and is both supplied as well as relieved through an external pilot circuit.

Benefits

• NBR seals for mineral oil of class HL in the usual temperature window, mass 12.5 kg.
• Nominal flow 250 l/min, maximum flow of the range 800 l/min.
• Spool position feedback plus control electronics inside the valve, ±10 V command value on a 24 VDC supply.
• External pilot oil supply with external return keeps pilot pressure independent of working pressure.
• Mounting pattern ISO 4401-07-07-0-05, spool symbol E, 3 switching positions, conformity CE.

Applications

The valve serves presses, lifting gear and test rigs built around size 16 interfaces. External pilot routing allows pilot pressure to be limited cleanly even while working pressure swings up to 350 bar. Axis control has 4 ports across 3 switching positions available.
