We know that directional control valves are manufactured on the most modern equipment and tested in all manufacturing cycles, starting with checking the quality of the casting housing and the gap between a pair of casing spools. High-precision spool manufacturing provides "zero leakage" during working pressure and minimal pressure drop when switching the position of the spool relative to the neutral position. The technical and design departments use high quality (hydraulic cast iron) and unique precision in the manufacture of each unit distributor, resulting in high performance and minimal steam leakage.
During use, attention should be paid to the oil leakage of the lever control valve. There are four main parts of oil leakage of the lever hydraulic control valve: first, the oil leakage at the joint surface of the hydraulic lever control valve itself and the bolt hole seal; The second is the oil leakage of the hydraulic lever control valve stem and valve sleeve; The third is the leakage of the quick coupling installed on the lever control valve, and the gasket on the joint surface of the quick coupling and the hydraulic lever control valve leaks oil; Fourth, hydraulic lever control valve joint installation surface gasket, oil inlet, oil outlet pipe oil leakage. Only by knowing the cause of the oil leak will you have the right way to repair the lever hydraulic control valve. When encountering related problems, if there is an experienced product after-sales, it will be twice as effective for solving the problem. Speaking of after-sales service, I have to introduce Hanjiu Technology Company to everyone.
