Proportional Directional Valve 4WRLD27E1-600LJ-4X/MXY/24ND6T - Bosch Rexroth R901524145

When an older valve is replaced the spool symbol has to match, otherwise the characteristic curve no longer fits the tuned control loop. This version carries the E1 spool symbol and, with 600 l/min nominal flow and 270 bar operating pressure, covers the same working range as the other size 27 variants.

Benefits

• E1 spool symbol - a direct replacement for axes engineered around this characteristic.
• 600 l/min nominal flow and up to 1850 l/min maximum flow at 270 bar operating pressure.
• Digital axis controller in the valve, analogue ±10 V command value on the 12-pole connector (11 + PE) to EN 175201-804.
• External pilot circuit with external supply and external return, subplate mounting to ISO 4401-08-08-0-05, 20.78 kg.

Application

The valve is intended for closed loop axes on presses and test benches whose engineering is fixed on the E1 symbol. External pilot oil routing makes sense when the working pressure varies strongly and the pilot stage has to stay independent of it. Design the circuit around HL hydraulic fluid and NBR seals.
