Product Overview
The Rexroth DRE20-61/200YG24K4M (Material Number R901240660) is a pilot-operated proportional pressure reducing valve designed for precise, infinitely variable pressure control in industrial hydraulic systems. Part of the Rexroth DRE series, this valve reduces a higher inlet pressure to a regulated, electrically proportional outlet pressure by means of a proportional solenoid acting on a pilot stage, which in turn controls the main spool. The integrated proportional solenoid converts an electrical current signal into a proportional mechanical force, enabling stepless pressure adjustment in direct relation to the command signal. This valve is engineered for demanding closed-loop and open-loop pressure regulation tasks where accurate, repeatable pressure reduction is essential, and it serves as a critical control element in manifold and inline hydraulic circuits across heavy industry.
