Construction machinery accessories LNRV-08 direct acting relief valve

In practical applications, the threaded cartridge valve is easier to meet the pressure requirements than other methods, but in many cases, the phenomenon of failing to meet the predetermined flow requirements. Under normal circumstances, the flow/pressure curve of the threaded cartridge valve is measured in the case of its calibrated maximum working port, according to the actual situation of most of the domestic hydraulic integrated block processing manufacturers, the processing accuracy of the equipment can not reach the accuracy required by the threaded cartridge valve jack, on the one hand, the accuracy of the main processing equipment, on the other hand, the selection of processing tools. Manual operation, rocking back drilling/lathe machining is relatively the most simple and feasible machining method of the jack, does not emphasize the error and precision control, this processing process is difficult to control the burr and flash in the processing. Although the threaded cartridge valve can effectively avoid leakage, it is also based on high-quality processing and scientific and advanced deburring technology. Relatively speaking, the design and production of the threaded cartridge valve block is stronger and more complex than that of the plate valve, superposition valve and tubular valve. We can add a filter device somewhere in the loop, but the most fundamental is the quality of the valve block body.
