Product details
DBEBE6X‑1X Proportional Pressure Valve
Product Overview
DBEBE6X‑1X is a pilot‑operated electro‑hydraulic proportional pressure‑relief Hydraulic valve, equipped with built‑in onboard electronics (OBE) and spool‑position closed‑loop feedback, widely used for high‑precision stepless remote pressure limiting and electronic pressure setting in industrial hydraulic system and automated industrial Machine.
This high‑accuracy proportional Hydraulic valve adopts internal pilot‑oil supply and compact NG6 size. It converts analog electrical control signals into infinitely‑variable maximum system pressure, realizing continuous pressure‑limit adjustment for the main circuit of your hydraulic system. Benefiting from closed‑loop position feedback control, it achieves ultra‑low hysteresis and excellent repeatability, delivering stable and reliable over‑pressure safety protection for downstream hydraulic actuators. It is an ideal high‑precision pressure‑control component for hydraulic test‑benches, injection‑molding machinery, CNC equipment and various hydraulic‑driven Machine.

Working Principle
DBEBE6X‑1X proportional pressure‑relief Hydraulic valve consists of proportional solenoid with position sensor, pilot valve and main‑stage spool assembly. After receiving electrical command signal, the built‑in electronic unit drives the proportional solenoid to generate corresponding thrust. The inductive position sensor feeds real‑time spool‑position signal back to the onboard amplifier, forming closed‑loop correction to eliminate friction‑caused control error. When pressure inside the hydraulic system rises to the preset value, the main spool opens P‑T passage and discharges excess hydraulic oil, so as to limit the maximum system pressure. The built‑in mechanical safety pressure‑limiting function provides backup protection for the whole hydraulic system even under electronic failure condition.
Damaged proportional solenoid, position‑sensor failure or onboard electronics malfunction will cause pressure drift, unstable pressure limiting, over‑pressure faults of the Machine. Replacing a qualified DBEBE6X‑1X proportional pressure valve can restore accurate closed‑loop remote pressure‑limiting performance of your hydraulic circuit.
Core Advantages
1. Closed‑loop spool‑position feedback greatly reduces hysteresis, significantly improving pressure‑setting precision and repeatability of your hydraulic system.
2. Integrated onboard electronics (OBE), no external amplifier required, simplifying wiring layout and saving cabinet space for compact‑size Machine.
3. Internal pilot‑oil supply, no extra external pilot pipeline needed, making the whole hydraulic system more concise.
4. Standard ISO sub‑plate mounting, good interchangeability, convenient for upgrading or retrofitting existing hydraulic circuits.
5. Built‑in mechanical emergency pressure‑limiting protection, enhancing operational safety of hydraulic‑driven industrial Machine.
Application Range
DBEBE6X‑1X proportional pressure‑relief Hydraulic valve is a high‑precision pressure‑control spare‑part for industrial hydraulic system. It is widely applied to hydraulic test‑benches, precision injection‑molding equipment, hydraulic presses, CNC machine‑tools, packaging machinery, automated production lines and other hydraulic‑driven industrial Machine. Suitable for hydraulic‑system integrators, equipment‑manufacturers, maintenance workshops and global spare‑parts distributors.
