Kadin is from Brazil. I know that he has purchased hydraulic cartridge valves from Ningbo for at least 2 years. The peers joked that his bargain just like cutting vegetables. But a batch of hydraulic pressure control cartridge valves made him suffer. The reason may be that the price was too low. In the second half of last year, they received feedback from customer that the excavator they sold, the stick and boom will fall a short distance after stop working. Their engineers judged that the load holding function of the hydraulic pressure control cartridge valve in the system was abnormal. The original manufacturer of the hydraulic pressure control cartridge valve said that it is too difficult to optimize the function due to its price. Kadin contacted other cartridge valve manufacturers and asked that the load holding function should be 100% guaranteed, and there was no result after a week. In this way, the original manufacturer did not care about the function of the hydraulic pressure control cartridge valve supplied, and the new manufacturers also ignored him. Kadin was in a hurry.
Kadin sent me an email: Can AAK 100% ensure that the hydraulic pressure control cartridge valve can maintain its load? After several rounds of communication, I learned that he had trouble in purchasing hydraulic pressure control cartridge valves. According to the video of equipment abnormalities complained by his customer and the production drawings of hydraulic pressure control cartridge valve, I fed back AAK's plan. Kadin asked for samples. After 45 days, AAK sent 24 samples of hydraulic pressure control cartridge valves.
3 months later, Kadin emailed me that it was nearly 3 months since AAK hydraulic pressure control cartridge valve was used, the customer did not find that the stick and boom were falling. His boss planned to replace the original manufacturer's hydraulic pressure control cartridge valves with AAK’s.
AAK 100% ensures that the hydraulic pressure control cartridge valve has load holding function, which depends on the structural innovation. During the load holding process, the conical valve spool and valve sleeve form a conical sealing structure under the pre-compression force of the return spring. This can effectively reduce the clearance leakage through the pilot spool spool and reduce the boom drift.
1. The hydraulic pressure control cartridge valve is equipped with a pilot sliding cone valve spool and a pilot oil passage. The valve body, valve sleeve and pilot spool valve spool cooperate with each other to form 6 chambers from left to right. There is a load oil circuit in the sixth chamber, which is connected with the fifth chamber through the first orifice and the second orifice. The fifth chamber is connected with the second chamber with the main valve body through the oil inlet hole.
2. The main valve body of the hydraulic pressure control cartridge valve has a one-way valve spool and a one-way valve spool spring chamber. The third chamber is connected with the spring chamber of the one-way valve spool through the throttling groove, and the spring chamber is connected with the second oil drain hole and oil drain passage.
3. The pilot control part provides the hydraulic pressure control cartridge valve with load holding relief pressure oil through the pilot oil passage, and the fourth chamber is connected with the oil drain passage through the first and second oil drain holes. When the load is maintained, a conical sealing structure is formed between the one-way valve spool and the main valve body.
AAK hydraulic pressure control cartridge valve, 100% load holding function, is not only safe, you can also try it!
