Cartridge Valves

Compact, Versatile Control Solutions for Hydraulic Systems

Cartridge valves are compact hydraulic components designed to be inserted into a standard cavity within a manifold block. Secured by screw threads or a bolted cover, they provide a highly efficient way to control fluid flow, pressure, and direction in hydraulic circuits. Their modular design allows for easy installation, replacement, and system customization.

At Hydraulics Online, we supply cartridge valves from a wide range of global manufacturers, with expert advice to help you select the right type for your application.

Cartridge valves are available in slip-in or screw-in designs and can perform multiple hydraulic functions, including:

Directional control – managing the path of fluid flow
Pressure control – regulating or limiting system pressure
Flow control – adjusting flow rates for precise operation
Load holding – check valves, counterbalance

Because they fit directly into manifold cavities, cartridge valves allow for compact system layouts and reduced external piping, improving reliability and reducing leakage risks.

Compact and modular design – saves space and simplifies system architecture
Versatile functionality – available for directional, pressure, and flow control applications
Easy installation and replacement – quick servicing without major system disruption
High reliability – fewer external connections reduce leakage and maintenance issues
Customisable options – wide range of valve types to suit specific performance needs

These advantages make cartridge valves a preferred choice in mobile, industrial, marine, and energy-sector hydraulic systems.

Cartridge valves are widely used in:

Their adaptability makes them suitable for both simple circuits and complex, multi-function hydraulic systems.

What’s the difference between slip-in and screw-in cartridge valves? Slip-in valves are inserted into cavities and secured with covers, while screw-in valves use threaded housings. Both offer compact installation but suit different design preferences.

Can cartridge valves replace traditional line-mounted valves? Yes – cartridge valves often reduce space requirements and improve reliability compared to line-mounted alternatives.

Do you supply proportional cartridge valves? Absolutely. We offer proportional cartridge valves for precise control of flow, pressure, and direction.
