Product details
3DREP(E)6‑2X Proportional Pressure Valve
Product Overview
3DREP(E)6‑2X is a direct‑operated 3‑way electro‑hydraulic proportional pressure‑reducing Hydraulic valve, widely used for high‑precision stepless remote pressure regulation of dual‑branch circuits in compact‑layout industrial hydraulic system and automated Machine .
This compact proportional Hydraulic valve includes two variants: 3DREP6‑2X for external amplifier drive, and 3DREPE6‑2X equipped with built‑in onboard electronics (OBE). Driven by double proportional solenoids, it converts analog electrical control signals into infinitely‑variable stable secondary pressure for two independent output ports, realizing flexible pressure control for multi‑loop hydraulic system. With low hysteresis, high repeat accuracy and fast dynamic response, it delivers reliable pressure‑control performance for precision‑required hydraulic‑driven Machine, such as injection‑molding auxiliary equipment, hydraulic test‑benches and automated production lines.

Working Principle
3DREP(E)6‑2X proportional pressure‑reducing Hydraulic valve consists of dual proportional solenoids, pressure‑measuring spool and main‑stage control spool assembly. After receiving electrical command signal, the corresponding proportional solenoid generates thrust to push the control spool, switching oil passage from inlet P to target output port A or B. The built‑in pressure‑measuring spool feeds back outlet pressure to balance solenoid thrust, keeping secondary pressure stable regardless of flow fluctuation inside the hydraulic system. When power is cut off, the spool automatically returns to central position, connecting both A and B ports to tank T and releasing residual pressure for the whole hydraulic system.
Damaged proportional solenoid, spool sticking or amplifier malfunction will cause pressure drift, unstable output pressure or pressure‑setting failure of the Machine. Replacing a qualified 3DREP(E)6‑2X proportional pressure valve can restore accurate dual‑loop remote pressure‑regulation performance of your hydraulic circuit.
Core Advantages
1. Stepless electric remote pressure adjustment for two independent branches, greatly improving automation and flexible pressure‑setting efficiency of your hydraulic system.
2. Direct‑operated compact NG6 design, small installation footprint, perfectly suitable for small‑and‑medium‑size integrated Machine.
3. Two optional control solutions: external amplifier or integrated OBE electronics, flexible to match different electrical cabinet layouts.
4. Standard ISO sub‑plate mounting dimension, strong interchangeability, convenient for upgrading or refitting existing hydraulic system.
5. Spring‑centered safety reset function, automatically releases residual pressure after power‑off, enhancing operational safety of hydraulic‑driven industrial Machine.
Application Range
3DREP(E)6‑2X proportional pressure‑reducing Hydraulic valve is a high‑precision pressure‑control spare‑part for compact‑layout industrial hydraulic system. It is widely applied to injection‑molding machinery, hydraulic test‑benches, packaging equipment, small‑and‑medium hydraulic presses, CNC auxiliary hydraulic stations, automated assembly lines and other hydraulic‑driven industrial Machine. Suitable for hydraulic‑system integrators, equipment‑manufacturers, maintenance workshops and global spare‑parts distributors.
