Structure and working principle of two way cartridge valve
 

      Two way cartridge valve features
Two-way cartridge valve is a multifunctional composite valve with the basic components of cartridge valve (spool, sleeve, spring and seal ring) inserted into a specially designed and processed valve body, and equipped with a cover plate and pilot valve. Because each cartridge valve basic component has and only two oil ports, it is called a two-way cartridge valve, and in the early days, it is also called a logic valve.
The two-way cartridge valve has the following characteristics: large flow capacity, small pressure loss, suitable for large flow hydraulic system; The main spool stroke is short, the action is sensitive, the response is fast, the impact is small; Strong anti-oil ability, no strict requirements for oil filtration accuracy; Simple structure, easy maintenance, less failure, long life; The plug-in has the characteristics of one valve and multiple energies, which is convenient to form various hydraulic circuits and work stably and reliably; The plug-in has a high degree of universality, standardization, serialization of parts, can form an integrated system.

The working principle and characteristics of cartridge valve
Cartridge valve is a kind of switch valve that uses small flow control oil to control large flow working oil. It is the main control component of the taper valve inserted in the oil block, so the name cartridge valve.

Cartridge valves are now mainly divided into two categories: the first type is the traditional cap plate cartridge valve, which appeared in the 1970s and is mainly used for high pressure and large flow occasions. Not suitable for small flow under 16 paths. Cartridge valve can not only realize various functions of ordinary hydraulic valve, but also has the advantages of small flow resistance, large flow capacity, fast operation speed, good sealing, simple manufacture, reliable operation and so on. The second type is the rapidly developed threaded cartridge valve on the basis of the safety valve in the multi-way valve of construction machinery, which just makes up for the lack of the cap plate cartridge valve that is not suitable for small flow, mainly for small flow occasions. The screw cartridge valve has various control functions, and the single component is inserted into the control block with the screw thread type, and the structure is very small and compact. In addition to the difference in the flow range, it has almost all the advantages of the cap plate cartridge valve, and can be widely used in various fields requiring hydraulic control of small flow.

Because of the simple structure, reliable work and high standardization of the cartridge valve, it is suitable for the integration of the hydraulic system, greatly reducing the pipeline connector and the leakage, vibration, noise and other faults caused by the pipeline, and can significantly reduce the size and quality of the large flow rate, high pressure and more complex hydraulic system.
