What is the working principle of cartridge valve?

There are many types of cartridge valves, and different types of cartridge valves have different working principles. Among them, the working principle of the two-way cartridge valve is that the cone valve unit is inserted into the valve body, and the control cover plate controls the opening and closing of the cone valve unit, so different cover plates can complete different jobs. The purpose of the cartridge valve is to directly communicate the control port of the reversing valve assembly with the oil port A or B through the channels on the valve block and the cover plate to form a one-way valve. What is the working principle of the specific cartridge valve and what are its applications? Let's take a look at it in the article! 1. What is the working principle of cartridge valve?

Cartridge valve is a big category, which refers to its installation method. The difference between it and different valves is that it can be directly connected with the nozzle, without other joints, and the installation is simple. Taking the working principle of this two-way cartridge valve as an example, this paper briefly introduces it.

The two-way cartridge valve is mainly composed of valve core, valve sleeve and spring. The control cover plate is provided with a control port communicated with the upper cavity of the poppet valve unit, and the poppet valve unit is inserted into the valve body with two channels (a and b), and the control cover plate controls the opening and closing of the poppet valve unit. By configuring different cover plates on the cone valve unit, different working functions can be realized.

2. What are the applications of cartridge valves?

In the industrial field that is often neglected, the application of cartridge valve is expanding. Especially in many occasions with limited weight and space, traditional industrial hydraulic valves are helpless, while cartridge valves show their talents. In some applications, cartridge valves are the only choice to improve productivity and competitiveness. The following is the application mode of cartridge valve:

1, check valve

The control port of the reversing valve assembly is directly communicated with the oil port A or B through the channels on the valve block and the cover plate to form a one-way valve.

2. Two-way valve

The two-position three-way electromagnetic slide valve can form a two-position two-way valve to control the oil circuit mode of the reversing valve assembly.

3. Three-way valve

It is composed of two directional valve components connected in parallel to form a pressure oil port, a working oil port and an oil return port. The number of working states of the three-way cartridge valve depends on the number of working positions of the pilot reversing valve.
