Stephen is from a hydraulic equipment manufacturing company in Greece, and his 3-year procurement is very successful. At the beginning of the year, their customer customized the company's large tonnage cranes, with very high requirements for hydraulic cartridge directional control valves. Stephen chose a local hydraulic cartridge valve manufacturer who has cooperated with him for 3 years to make samples. During the prototype debugging, the connecting pipeline of the oil cylinder burst, causing the boom to drop abnormally. Their engineers advised that the key is to optimize the load balance of the hydraulic cartridge directional control valve. The manufacturer said that this hydraulic cartridge directional control valve benchmarks a standard part of HydraForce and cannot be improved. Stephen contacted more than 10 hydraulic cartridge valve manufacturers, but none of them was willing to improve the standard parts of HydraForce. Stephen was very worried.
Stephen found AAK while browsing Google. He noticed that AAK was continuously supplying HydraForce and left a message: Can AAK optimize the hydraulic cartridge directional control valve of HydraForce standard parts? I guess that he encountered trouble in purchasing hydraulic cartridge directional control valves. After communication, I learned the story above. According to his hydraulic schematic diagram, production drawings of hydraulic cartridge directional control valve, and equipment work videos, AAK engineer said that the original system was designed as a double cylinder luffing structure. During the luffing operation, the cylinder motion was not synchronous. When the system was suddenly loaded, the double cylinders were biased and the pipeline burst. Only by optimizing the structure of the hydraulic cartridge directional control valve can the load balance of the system be improved. Stephen saw the hope and paid the development cost on the second day. After 35 days, AAK sent 12 samples of hydraulic cartridge directional control valves.
2 weeks later, Stephen informed by email that after replacing with AAK hydraulic cartridge direction control valves, the prototype debugging was smooth, no pipeline burst, and the equipment had been delivered to the customer. After the customer tried, there would be an official order.
AAK optimized the structure of the hydraulic cartridge directional control valve, and set small tricks on the first and second oil ports of the valve body. The oil passage between the first oil port and the valve chamber is equipped with a detachable damper, and the inner wall of the valve chamber at one side of the second oil port is provided with a boss extending radially. After this optimization, the oil pressure connected to the first oil port and the second oil port of the valve can act on both ends of the valve spool respectively, and the valve spool can slide between the first working position and the second working position under the action of the pressure oil. When the valve spool is in the first working position, the first oil port of the valve body is connected to the second oil port, and when the valve spool is in the second working position, the oil path between the first oil port and the second oil port of the valve body is not connected.
AAK hydraulic cartridge directional control valve, no longer need to worry about safety, you can also try a small order!
