Solenoid On/Off Cartridge Valve
(Including key words: hydraulic system, hydraulic cartridge valve)
1. Product Overview
The solenoid on/off cartridge valve is a threaded screw-in cartridge type hydraulic valve, specially designed for integrated hydraulic system. This compact solenoid valve is installed directly into valve blocks via threaded cartridge structure, replacing bulky manifold mounted directional valves. It is used to switch hydraulic circuit on and off rapidly, controlling the oil flow of actuators such as cylinders and hydraulic motors. With small installation size, fewer external pipeline connections and low leakage characteristics, it is widely used in engineering machinery, agricultural equipment, sanitation trucks, material handling machines and compact hydraulic power units. Standard industry thread dimensions allow interchangeability with international brand cartridge valves.
Model Explanation
Solenoid On/Off Cartridge Valve refers to screw-in threaded cartridge valve with electromagnetic switch function for circuit opening and closing control.

3. Working Principle
When the solenoid coil is energized, electromagnetic force pushes the valve spool to shift, opening or blocking the internal oil passage inside the cartridge valve. When power is cut off, the built-in return spring resets the spool and switches the hydraulic circuit status. This valve realizes reliable on-off control of the hydraulic system, cutting off pressure oil flow to lock cylinders or stop hydraulic motors instantly. The cartridge design eliminates external pipe connections and greatly reduces external leakage points.
4. Core Advantages
1. Compact screw-in cartridge design, saves much space inside valve manifold blocks.
2. Minimal external leakage, fewer fittings and simplified system layout.
3. Fast response switching, stable operation with low noise.
4. Modular design, easy replacement without disassembling the whole valve block.
5. Good anti-vibration performance, suitable for mobile machinery working conditions.
6. Multiple voltage options for different global market requirements.
7. Interchangeable with international standard cartridge valves.
5. Application Range
This cartridge solenoid valve is widely integrated into hydraulic system of mini excavators, loaders, road sweepers, garbage trucks, forklifts and compact hydraulic power packs, used for circuit cut-off, cylinder locking and flow switch control.
6. Common Faults & Replacement Advice
Replace the cartridge valve assembly if these issues occur: valve fails to switch, internal leakage causes cylinder drifting, coil burnout, oil leakage from thread portion.
