Rexroth Z2S10‑1‑30B Sandwich Stack Valve
Product Overview
The Rexroth Z2S10‑1‑30B is a high‑performance stacked Hydraulic valve, which is a typical sandwich‑type hydraulic control component widely used in industrial and mobile hydraulic system. As a pilot‑operated check valve with stacked installation design, this Hydraulic valve realizes pressure holding, oil circuit locking and backflow prevention functions, effectively maintaining the pressure stability of the executive circuit and avoiding uncontrolled action of the Machine. It adopts NG10 (CETOP 05) standard sandwich installation size, which can be freely combined with other directional valves, pressure valves and flow valves to build a compact integrated hydraulic manifold block. The reliable sealing and precision spool structure ensure long‑term stable operation under high‑pressure working conditions, greatly improving the safety and stability of the whole hydraulic system. It is suitable for injection molding machines, hydraulic presses, construction machinery and other equipment for OEM assembly, maintenance replacement and system transformation.

Working Principle
When the main oil circuit of the hydraulic system supplies pressure oil, the oil can pass through the one‑way channel of the Hydraulic valve smoothly. When the system pressure needs to be maintained, the pilot pressure oil pushes the internal spool to open the reverse channel only when external pilot pressure is applied; otherwise, the reverse oil flow is completely locked, keeping the pressure of the actuator cylinder stable and preventing the Machine from drifting or moving accidentally. If the internal sealing ring or spool of the valve is worn, it will lead to pressure leakage, pressure holding failure and unstable action of the equipment. Replacing the qualified Rexroth Z2S10‑1‑30B can restore the circuit locking function and ensure the normal operation of the hydraulic system.
Core Advantages
1. Rexroth original hydraulic technology, stable pressure bearing performance, effectively guarantees the pressure holding reliability of the hydraulic system.
2. Sandwich stacked design, simplifies the pipeline layout of the hydraulic station, reduces the overall volume of the hydraulic integrated block, and optimizes the installation space of the Machine.
3. Low‑pressure‑drop internal flow channel design, reduces energy loss and heat generation during oil passing, improves the energy efficiency of the whole system.
4. High‑precision machining of spool and matching parts, strong anti‑pollution ability, adapts to the complex working environment of industrial production and construction machinery.
5. Standard NG10 interface, universal with most mainstream hydraulic valve groups, convenient for maintenance and replacement without modifying the original manifold.
Application Range
Z2S10‑1‑30B pilot operated check Hydraulic valve is an important auxiliary control component for the hydraulic system. It is widely used in injection molding machines, hydraulic bending machines, construction machinery hydraulic circuits, automated production lines and other hydraulic‑driven Machine. It is applicable to equipment manufacturing factories, hydraulic system maintenance workshops and spare parts suppliers for routine maintenance and system upgrading.
