Proportional Directional Valve 4WRTE25V1-350L-4X/6EG24EK31/F1M - Bosch Rexroth R901093689

Back pressure in the tank line disturbs the pilot stage of a closed-loop valve. Here the pilot oil return runs externally and therefore without back pressure, while the supply stays internal. Nominal flow is 350 l/min.

Benefits

• External pilot return keeps the pilot stage free of main-circuit back pressure
• Internal supply, so only one extra line is needed on the manifold
• Nominal flow 350 l/min, up to 870 l/min through the valve at 350 bar
• Internal spool position feedback with a linear characteristic
• Command value 4...20 mA, V1 spool
• Weight 17.9 kg, 7-pole (6 + PE) connector to EN 175201-804

Application

The variant is used in plants with long return runs and coolers in the tank circuit, such as rolling mills and large presses. The on-board electronics handle position control and output stage. HL is the intended hydraulic fluid, sealed with NBR.
