In the construction machinery industry, hydraulic valves are used to control various functions of excavators, bulldozers, cranes, loaders and other machines used to dig, lift and move heavy objects. They are also used in various lifting and mixing equipment. Hydraulic valves play a key role in improving the performance and efficiency of construction machinery.

In industrial hydraulic systems, the application of threaded cartridge valve plugs (screw plugs) is crucial, and their design must meet stringent requirements such as high pressure, long-cycle operation, and media compatibility.

In the maintenance and modification of hydraulic valve groups, threaded cartridge valve plugs are key functional seals, and their application is directly related to system reliability, maintenance efficiency and modification costs.
