2 months ago, Jackson from the United States left a message on AAK website: I read the article "The throttling groove is changed from double to single triangle. The hydraulic counterbalance valve has no vibration. AAK makes Henry feel at ease for vacation". I feel that your hydraulic valve engineers are creative in the original design. I have a hydraulic pressure control valve. I always feel that the design is not perfect. Are you interested in redesigning it?
I like to read the user's message. The first thing I do when I open the computer is to read the message and then look at the inquiry. The inquiry with "difficult and complicated problems" will facilitate the transaction. I suggest Jackson send the hydraulic pressure control valve drawings, hydraulic schematic diagrams, and the problems encountered in the current procurement of hydraulic pressure control valves.
It turns out that Jackson is from a material handling hydraulic equipment company in the United States, and he has been engaged in procurement for many years and has been purchasing very smoothly. This time, he encountered a big difficulty on the hydraulic pressure control valve purchased. 1 year ago, Jackson’s company developed a hydraulic loader. After the trial, the customer advised that the sensitivity was not high during the operation process, so it was not needed any more. Their sales director was very angry and blamed the purchasing department for dragging his feet. After testing, the field engineer think that the probable cause of the problem is that the hydraulic pressure control valve has no pressure compensation function and the opening and closing speed of the valve is not ideal. So the engineer redesigned the hydraulic pressure control valve and optimized the whole hydraulic system. After 1 month, the newly designed hydraulic pressure control valve was installed and debugged. The operator reported that the equipment had been improved a lot, but he always felt that it was not perfect enough to buy. The sales director directly complained to the boss. Jackson had to constantly look for new manufacturers of hydraulic pressure control valves, but there was no substantive harvest.
After half a day of analysis, AAK engineers finally found the key points. I replied to Jackson that AAK would redesign the hydraulic pressure control valve to solve the sensitivity problem he encountered. After 40 days, AAK sent 6 hydraulic pressure control valve samples. 2 weeks later, Jackson emailed us that the sensitivity of the equipment was improved by at least 30% with the new hydraulic pressure control valve designed by AAK. The user was also very satisfied and was willing to buy the equipment. The boss was very happy.
The hydraulic pressure control valve newly designed by AAK belongs to the built-in zero leakage pressure compensation valve, which realizes the "zero leakage" load maintenance and the falling speed is not affected by the external load. When unloading, the hydraulic pressure control valve cuts off the signal branch, and no oil in the unloading signal branch flows back to the oil tank under high pressure, completely eliminating this part of energy loss, thus achieving the effect of accurate control, And the annual energy saving of the hydraulic loader can also reach about 10%.
AAK hydraulic pressure control valve, high sensitivity and energy saving, accuracy tolerance 1μm., opening and closing for 1 second, you can also try it!
