Zander is from a hydraulic manufacturing company in Greece. In the first half of this year, their company planned to upgrade the old logistics crane and put it back on the market. Its main goal is to improve its stability by 20% compared with its peers. The optimization of the hydraulic cartridge counterbalance valve is the key, but the original hydraulic cartridge counterbalance valve manufacturer has no ability to innovate. Zander found a local hydraulic cartridge valve manufacturer to optimize the structure and make samples. However, during commissioning, when the load of the system drops, the pressure fluctuation cannot exceed that of the peers, and the hydraulic cartridge counterbalance valve cannot avoid load interference. The local hydraulic cartridge valve manufacturer has no ability for further improvement. 2 months passed by, but there was still no solution. The boss pushed for progress many times, and Zander was worried.
Zander found AAK on Google, noticed that AAK had released some customer cases about hydraulic cartridge counterbalance valves, and sent us an email. According to the schematic diagram of the hydraulic system and the original hydraulic cartridge counterbalance valve drawing provided by him, AAK engineer informed that the structure optimized by his local hydraulic cartridge valve manufacturer was not reasonable and needed to be adjusted. AAK has a trick to prevent the hydraulic cartridge counterbalance valve from being affected by the load. Zander asked for AAK samples. After 45 days, AAK sent 20 samples of hydraulic cartridge counterbalance valves.
3 months later, Zander sent an order for 500 hydraulic cartridge counterbalance valves, and told us that their technical department was very satisfied with AAK hydraulic cartridge counterbalance valves. Not only did they overcome the load impact, but also improved the stability of their new logistics crane by more than 20%. In the promotion stage, the booking was good, and the boss was happy.
AAK hydraulic cartridge counterbalance valve can stably control the opening of the valve spool without being disturbed by the load, and its stability is higher than that of its peers, because we have tricks on optimizing the structure.
AAK hydraulic cartridge counterbalance valve is composed of a valve body, a valve seat, a main valve spool, a pilot valve spool and a pilot mechanism. The valve seat is connected with the valve body and forms a connected first channel. The extended end of the valve seat butts against the pilot mechanism and forms a second channel. The main valve spool is provided with a throttling slot. One end of the pilot valve spool slides and is arranged in the inner cavity of the main valve spool. The other end is connected with the pilot mechanism. The pilot valve spool is equipped with a throttling slot. The pilot valve spool is connected with the inner cavity of the main valve spool as a balanced structure. The force of the pilot mechanism can balance the oil pressure in the oil passage on the pilot valve spool. Therefore, the opening of the main valve spool is not affected by the load pressure wave.
AAK hydraulic cartridge counterbalance valve, free from load interference, you can also have a small try!
