Bosch Rexroth DBEME10-7X/350YG24K31A1V proportional pressure relief valve

DBEME10-7X/350YG24K31A1V (material number R901356058) is a Bosch Rexroth DBEME pilot-operated proportional pressure relief valve, nominal size 10, series 7X, for subplate mounting to ISO 6264. Its FKM seals and integrated control electronics are identified by the factory designation.

The pressure class is up to 350 bar; this is a command-pressure class, not an individual delivered setting. The main stage relieves P to T. An additional maximum-pressure limiter protects against pilot-valve error. The external pilot return Y must connect separately to the tank at zero pressure. This Y execution has no external unloading port X.

Integrated electronics use the A1 0–10 V command interface and a nominal 24 V DC supply within 21–35 V DC, with current consumption up to 1.5 A. The minimum supply voltage at the power unit also depends on cable length and conductor cross-section. The mating connector, subplate and specified mounting screws are separately ordered.

For the 1600 mA version, the hydraulic reference uses HLP46 at 40 ±5 °C: port P (and external X on XY executions) is limited to 350 bar, port T to 315 bar, and nominal size 10 has a maximum flow of 275 L/min. The reference fluid envelope is −20 to +80 °C and 15–380 mm²/s; cleanliness is ISO 4406 20/18/15. Other fluids can impose lower pressure, temperature and service-life limits. In particular, water-containing HFC requires NBR seals, a maximum 210 bar differential per control edge and fluid temperature no higher than 60 °C. Ambient limits are −20 to 50 °C. Minimum setting pressure is flow-dependent, not zero at zero command.
