ZDRE10VP‑2X Proportional Pressure Valve
Product Overview
ZDRE10VP‑2X is a pilot‑operated sandwich‑mounted electro‑hydraulic Hydraulic valve, widely used for stepless, electric remote pressure regulation in sub‑circuit of industrial hydraulic system and automated industrial Machine.
This proportional pressure‑reducing Hydraulic valve belongs to Rexroth ZDRE series with nominal size NG10. It converts analog electrical control signal into infinitely‑variable output pressure, independently and precisely adjusting the secondary‑circuit pressure of your hydraulic system, separating high‑pressure main circuit from low‑pressure actuator branch. Featuring stable pressure output, low hysteresis and good linearity, it realizes flexible remote pressure setting for multi‑pressure‑loop equipment, an ideal pressure‑control component for injection molding machines, hydraulic presses, machine tools and automated hydraulic‑driven Machine .

Working Principle
ZDRE10VP‑2X proportional pressure‑reducing Hydraulic valve is installed between two hydraulic valve plates. After receiving the electrical command signal, the proportional solenoid outputs corresponding thrust, controlling the pilot pressure. The pilot pressure acts on the main spool to adjust the opening gap between inlet port and outlet port, reducing the high‑pressure oil from main circuit to preset lower secondary pressure, and maintaining stable output pressure regardless of flow fluctuation. It provides independent pressure protection and pressure‑setting function for partial actuators inside the hydraulic system.
Solenoid aging, spool sticking or amplifier failure will lead to pressure drift, unstable pressure‑output, pressure‑loss or over‑pressure fault of the Machine. Replacing a qualified ZDRE10VP‑2X proportional pressure valve can restore accurate remote pressure‑control performance of your hydraulic sub‑circuit.
Core Advantages
1. Stepless electrical remote pressure regulation, greatly improving automation and flexibility of pressure‑setting for your hydraulic system.
2. Sandwich stack‑plate installation, space‑saving layout, convenient to combine with directional valves, flow valves and other hydraulic components.
3. Excellent pressure‑holding performance and low hysteresis, ensuring long‑term stable pressure output of actuator branch circuit.
4. NG10 standard superposition dimension, strong interchangeability, easy to upgrade or refit existing hydraulic system.
5. Pilot‑operated structure, large‑flow capacity, suitable for medium‑and‑heavy‑load hydraulic‑driven Machine.
Application Range
ZDRE10VP‑2X proportional pressure‑reducing Hydraulic valve is a core pressure‑control accessory for multi‑loop industrial hydraulic system. It is widely applied to injection‑molding machinery, hydraulic presses, CNC machine‑tools, hydraulic test‑benches, metallurgical automation equipment, material‑handling machinery and other hydraulic‑driven industrial Machine. Suitable for hydraulic‑system integrators, equipment‑manufacturers, maintenance workshops and global spare‑parts distributors.
