Solenoid Cartridge Valves
Product Overview
Solenoid Cartridge Valves are high‑efficiency Hydraulic valve. As an electrically‑actuated CARTRIDGE VALVE, it completes remote on‑off and direction switching for oil flow within the hydraulic system. It controls the start, stop and movement direction of actuators on the Machine. This insert‑in CARTRIDGE VALVE can be directly assembled into manifold blocks, cutting down piping connections, saving installation space and lowering leakage risks.

Working Principle
This Hydraulic valve combines electromagnetic drive with cartridge valve body. When energized, the solenoid pushes the internal spool or poppet inside the CARTRIDGE VALVE to shift position. It opens or closes oil passages and changes oil flow path of the hydraulic system.
By receiving electrical control signals, the valve remotely drives hydraulic cylinders and hydraulic motors on the Machine to perform different actions. De‑energized status resets the valve position through built‑in return spring. Thanks to the integrated cartridge structure, complicated external valve blocks and pipe connections are omitted, achieving fast response for automatic hydraulic loops.
Key Advantages
1. Standard CARTRIDGE VALVE compact structure, easy integration into manifold, greatly simplifies the whole hydraulic system.
2. Electric signal remote control, convenient for automatic and centralized operation of the Machine.
3. Fast switching response, stable action for frequent cycle working conditions.
4. Simple maintenance: replace cartridge insert or solenoid coil separately without disassembling complete manifold.
5. Excellent anti‑pollution performance, adaptable to harsh working environment of engineering equipment.
Application Scope
This key Hydraulic valve is widely adopted in the hydraulic system of various Machine: excavators, loaders, cranes, agricultural machinery, material‑handling machines, hydraulic power packs and special‑purpose industrial facilities. Typical circuits: automatic direction switching, remote on‑off control, hydraulic locking, unloading control, safety interlock protection loop.
