Product details
DBETR‑10 Proportional Pressure Valve
Product Overview
DBETR‑10 is a direct‑operated poppet‑type electro‑hydraulic proportional relief Hydraulic valve with inductive spool‑position closed‑loop feedback, widely used for stepless remote pressure limiting and electronic pressure setting in industrial hydraulic system and automated industrial Machine.
This high‑precision proportional Hydraulic valve adopts closed‑loop position feedback on the proportional solenoid assembly, requiring external drive amplifier. It converts analog electrical control signals into infinitely‑variable maximum system pressure, realizing continuous electronic pressure adjustment for the main circuit of your hydraulic system. Thanks to built‑in position‑sensor closed‑loop control, it achieves extremely low hysteresis and outstanding repeat accuracy, delivering stable over‑pressure protection and flexible multi‑pressure setting for hydraulic circuits. It is an ideal pressure‑control component for hydraulic power‑packs, injection‑molding machinery, hydraulic test‑benches and various hydraulic‑driven Machine.

Working Principle
DBETR‑10 proportional relief Hydraulic valve consists of proportional solenoid with inductive position sensor, poppet spool and spring assembly. After receiving electrical command signal, the proportional solenoid generates corresponding thrust to compress the spring. The built‑in inductive sensor feeds real‑time spring‑seat displacement signal back to external amplifier, forming closed‑loop correction to eliminate friction‑caused control error. When system pressure inside the hydraulic system rises to the preset value, hydraulic force pushes the poppet spool open, discharging excess oil to limit maximum system pressure. In case of power‑off or signal‑loss fault, the valve automatically resets to minimum pressure, providing basic safety protection for the hydraulic system.
Damaged proportional solenoid, position‑sensor failure, poppet spool sticking or amplifier malfunction will cause pressure drift, unstable pressure limiting, over‑pressure or pressure‑setting failure of the Machine. Replacing a qualified DBETR‑10 proportional pressure valve can restore accurate closed‑loop remote pressure‑limiting performance of your hydraulic circuit.
Core Advantages
1. Inductive position closed‑loop feedback greatly reduces hysteresis, improves pressure‑setting repeatability and control precision of your hydraulic system.
2. Poppet‑seat direct‑operated structure delivers fast dynamic response, compact NG6 size, suitable for pilot‑control circuits of small‑and‑medium‑size Machine.
3. Fault‑safe design: power‑off or signal‑loss will revert to minimum pressure, improving operational safety of the whole hydraulic system.
4. Standard ISO sub‑plate mounting, good interchangeability, convenient for upgrading or retrofitting existing hydraulic circuits.
5. Stable pressure‑limiting performance, ideal for frequent pressure‑adjustment working conditions of industrial Machine.
Application Range
DBETR‑10 proportional relief Hydraulic valve is a core high‑precision pilot‑pressure‑control spare‑part for industrial hydraulic system. It is widely applied to hydraulic power‑packs, hydraulic test‑benches, injection‑molding auxiliary equipment, packaging machinery, small‑and‑medium hydraulic presses and other hydraulic‑driven automated Machine. Suitable for hydraulic‑system integrators, equipment‑manufacturers, maintenance workshops and global spare‑parts distributors.
