Characteristic Description
What is a Cartridge Relief Valve?
A cartridge solenoid valve is an electrically controlled hydraulic valve designed in a compact screw-in cartridge form. It is installed directly into a manifold and used to control the flow direction, start/stop functions, or switching of hydraulic circuits.
Compared with traditional valves, cartridge solenoid valves offer a more compact structure, reduced leakage points, and easier integration into modern hydraulic systems. They are widely used in applications requiring fast and reliable electronic control.
How Does a Cartridge Relief Valve Work?
A cartridge solenoid valve operates by converting electrical energy into mechanical movement to control fluid flow. When the solenoid coil is energized, it generates a magnetic field that moves an internal plunger or spool. This movement changes the flow path inside the valve—either opening, closing, or redirecting the hydraulic fluid. When power is removed, a spring returns the valve to its original position.
This simple but effective mechanism allows precise and rapid control of hydraulic systems, making it ideal for automated and remote-controlled applications.

Direct acting cartridge relief valves function by directly balancing the hydraulic system pressure against a spring force. When system pressure exceeds the preset value, the valve opens instantly to relieve excess pressure, preventing damage. Their simple design and rapid response make them ideal for low-flow, compact systems where fast pressure relief is critical.
Pilot operated cartridge relief valves feature a two-stage design, using a pilot valve to control the main spool. This setup allows higher flow rates and more stable pressure regulation. They are especially suitable for high-pressure hydraulic systems, providing smooth operation, accurate pressure control, and reduced system shock during load changes or transient conditions.
Pressure reducing cartridge valves are designed to maintain a constant reduced pressure in a specific section of a hydraulic circuit, independent of upstream pressure fluctuations. This ensures sensitive components operate safely and consistently. They are widely used where precise control of downstream pressure is necessary, improving system stability and protecting equipment from overpressure.
Sequence and counterbalance cartridge valves regulate the order of operations in multi-actuator systems or control load-holding functions. Sequence valves ensure actuators operate in a defined order, while counterbalance valves prevent loads from dropping uncontrollably. They enhance safety, provide precise motion control, and protect hydraulic components under varying load conditions.
