Rexroth DB20-1-5X/100X Proportional Valve - 100 Bar, Blue, Electric

The Rexroth Proportional Valve DB20-1-5X/100X is a high-performance pilot-operated proportional pressure valve manufactured by Bosch Rexroth in Germany. This valve belongs to the proportional control valve series and can continuously and infinitely adjust the pressure of a hydraulic system based on the input electrical signal.

This valve is a pilot-operated proportional pressure valve with a nominal bore of 20 mm. It features single-stage pilot control. This valve belongs to the 5X series, featuring specific electrical interfaces and control characteristics. The valve has a rated pressure of 100 bar.

The valve employs a pilot-controlled structure, where the position of the pilot valve spool is adjusted by the magnetic force generated by the proportional solenoid, thereby controlling the opening of the main valve spool to achieve precise regulation of hydraulic system pressure. This design enables the valve to continuously adjust pressure in response to changes in the input electrical signal, thereby avoiding the hydraulic shock issues associated with traditional on/off valves.
