DRE6X‑1X Proportional Pressure Valve
Product Overview
DRE6X‑1X is a pilot‑operated 3‑way electro‑hydraulic proportional pressure‑reducing Hydraulic valve, widely used for stepless electric remote pressure regulation of branch circuits in medium‑size industrial hydraulic system and automated Machine .
This compact proportional Hydraulic valve features internal pilot‑oil supply, with DRE6X‑1X requiring external drive amplifier; the variant DREBE6X‑1X is equipped with built‑in onboard electronics (OBE). It converts analog electrical control signals into infinitely‑variable secondary output pressure, reducing high‑pressure oil from main circuit to preset stable working pressure for downstream actuators, and provides built‑in pressure‑limiting protection. With low hysteresis and good pressure‑holding performance, it delivers independent pressure control for multi‑loop hydraulic system, serving as a reliable pressure‑control component for injection‑molding machines, CNC machine‑tools, test benches and other hydraulic‑driven industrial Machine.

Working Principle
DRE6X‑1X proportional pressure‑reducing Hydraulic valve consists of pilot proportional solenoid, pilot control valve and main‑stage spool assembly . After receiving electrical command signal, the proportional solenoid generates corresponding thrust to adjust pilot pressure. The pilot pressure pushes the main spool to change the opening gap between inlet P and outlet A, reducing main‑circuit high‑pressure oil to target secondary pressure and maintaining stable outlet pressure regardless of flow fluctuation inside the hydraulic system. The built‑in pressure‑limiting function will open A‑to‑T passage to limit outlet pressure when over‑pressure occurs, protecting downstream actuators .
Damaged proportional solenoid, spool sticking or amplifier failure will cause pressure drift, unstable output pressure or over‑pressure faults of the Machine. Replacing a qualified DRE6X‑1X proportional pressure valve can restore accurate remote pressure‑regulation performance of your hydraulic branch circuit.
Core Advantages
