Product Overview
The Rexroth DBE 6-2X/315G24K31A1V (Material No. R901385108) is a pilot-operated proportional pressure relief valve from the proven DBE series, designed for precise, infinitely variable pressure control in industrial hydraulic systems. The valve limits system pressure by converting an electrical command signal into a proportional hydraulic pressure setting, allowing stepless adjustment of the pressure level rather than fixed, factory-preset relief behavior. Its compact 6-size (NG6 / CETOP 3) sandwich-style body integrates a proportional solenoid pilot stage with a balanced main spool, delivering fast response, low hysteresis, and excellent repeatability. As a direct-controlled proportional relief valve, it is widely used as a pressure-setting, pressure-limiting, or unloading element in circuits where dynamic pressure profiles and remote electrical control are required. The “315” designation indicates a maximum adjustable pressure of 315 bar, while the “G24” code specifies a 24 V DC proportional solenoid with the standard Rexroth electrical interface.
