Cartridge Valves


www.nb-major.com In order to keep up with the expansion of our business and meet the market demand, we set up NingBo Major Hydraulic Co., Ltd. (迈亿欧液压) in 2013 to produce screw-in cartridge valves and launch more than 80 new models every year. For details, please visit www.nb-major.com

Product details


Cartridge valve is a type of valve that offers several advantages in hydraulic and fluid power systems. It is designed with a compact and modular construction. The cartridge valve consists of a valve body and a cartridge insert which contains the valve’s internal components such as the spool or poppet.
One of the main features of the cartridge valve is its ease of installation and replacement. Since it has a modular design, it can be easily inserted into a valve block or manifold. This simplifies the assembly process of hydraulic systems, reducing the time and effort required for installation. In case of a valve failure, the cartridge can be quickly removed and replaced without having to disassemble the entire valve system.
Cartridge valves are available in different types, including pressure-control, flow-control, and directional-control cartridge valves. The pressure-control cartridge valve can regulate the pressure in the hydraulic system, preventing over - pressure situations which could damage the system components. The flow-control cartridge valve, as the name implies, is used to control the flow rate of the fluid. It can be adjusted to allow a specific amount of fluid to pass through the valve, which is important for applications where precise fluid control is required, such as in some automated manufacturing processes.
The directional-control cartridge valve determines the direction of the fluid flow in the hydraulic system. It can switch the flow path between different ports, enabling the control of hydraulic actuators like cylinders or motors. Cartridge valves are often used in applications where space is limited due to their compact size. They are also known for their high reliability and performance. Their design allows for efficient fluid handling, with minimal leakage and energy loss. In modern hydraulic systems, cartridge valves play an important role in achieving accurate and efficient control of fluid power.
