Product Overview
The Rexroth DBET-11/250HG24-8K4V (Material No. R901522581) is a direct-operated proportional pressure relief valve designed for precise, infinitely variable pressure control in industrial hydraulic systems. As a member of the Rexroth DBET series, this valve combines a proportional solenoid actuator with a seat-type poppet design, enabling stepless adjustment of system pressure in proportion to the electrical command signal. The valve functions as a pilot-operated pressure limiting device in the main pressure line, providing smooth pressure ramp-up and controlled relief of excess flow back to tank. With a nominal pressure rating of 250 bar and a 24 VDC proportional solenoid, the DBET-11/250HG24-8K4V is engineered for demanding applications requiring accurate pressure regulation, low hysteresis, and high repeatability.
