Proportional pressure relief valve DBEM20-7X/100YG24K4M

DBEM20-7X/100YG24K4M, manufacturer material number R901353029, is a Bosch Rexroth pilot-operated proportional pressure relief valve of nominal size 25, series 7X, with NBR seals and subplate mounting. The additional maximum-pressure limiter protects against pilot-valve error. Its delivery adjustment is not identified for this individual article; no factory preset is inferred.

The printed pressure class permits command-dependent setting up to 100 bar. Ports P and X have a 350 bar mineral-oil operating limit; port T is limited to 315 bar. The external pilot return Y must connect separately to the tank at zero pressure. Maximum flow is 550 L/min under the published reference conditions.

Its 1600 mA proportional solenoid requires separately ordered, current-regulated external control electronics. G24 is the factory voltage class; it does not mean that direct 24 V switching provides proportional pressure control. The mating connector, subplate and mounting screws are separately ordered.

Hydraulic reference data use HLP46 at 40 ± 5 °C and the 1600 mA coil. Other hydraulic fluids have separate material and pressure restrictions. The original manufacturer publication is RE29361, edition 2013-07; this archived edition establishes the stated technical reference, rather than a claim of a newer edition. Actual system settings are not determined by the model code.
