Product Overview
The Rexroth DBET-62/200G24-8K4V (Material Number R901170278) is a high-performance proportional pressure relief valve designed for precise, infinitely variable pressure control in demanding industrial hydraulic systems. As part of the Rexroth DBET series, this valve functions as a pilot-operated proportional pressure relief valve, utilizing a proportional solenoid to modulate the poppet position and thereby regulate system pressure in direct proportion to the electrical input signal. This design enables smooth, stepless pressure adjustment and reliable system protection against overpressure. The DBET-62/200G24-8K4V is engineered for applications requiring fast response, low hysteresis, and excellent repeatability, making it a critical component in modern electro-hydraulic control architectures.
