Phoebe comes from Greece, and has been purchasing hydraulic valves from Ningbo for 2 years. At the end of last year, their hydraulic power unit required a hydraulic pressure control valve, and Phoebe tested the sample from a cartridge valve manufacturer that had been cooperating for 2 years. During debugging, the equipment was unstable in operation, and it was found on site that it was rooted in the internal cone angle error of the hydraulic pressure control valve and the excessive axial grinding tolerance of the sealing circle. The original hydraulic pressure control valve manufacturer re-made samples two times, but the machining accuracy of the hydraulic pressure control valve still did not meet the standard. Phoebe realized that she needed to change the manufacturer of the hydraulic pressure control valve. After trying with another hydraulic pressure control valve manufacturer, the problem was not completely resolved for a month, and the boss was very angry that Phoebe was in a hurry and became anxious.
In early March, Phoebe approached me through an introduction from peers in Ningbo. The first sentence of her email was: Can you ensure that each hydraulic pressure control valve is 100% leak free? For similar messages, AAK always gives reply as soon as possible, as the other party must have encountered difficulties in purchasing hydraulic pressure control valves. After communication, it was learned that the accuracy of the hydraulic pressure control valves produced by both previous manufacturers did not meet the standards. The root cause of the problem has been identified. Ensuring the hydraulic pressure control valve is 100% leak free is not difficult for AAK. AAK can make samples, and if the samples do not meet the standards, all fees can be refunded. After 35 days, AAK sent 10 samples of hydraulic pressure control valves.
Today, Phoebe sent a PO for 300 hydraulic pressure control valves. Excitedly, the equipment has been running stably, and their engineer is satisfied with the machining accuracy of AAK hydraulic pressure control valve. The boss also praised her.
AAK processed it in this way. AAK uses the TSUGAMI CNC precision automatic lathe imported from Japan, which can control the machining accuracy of each valve cage within 2 μm. At the same time, during the production process, the application of detection devices can capture test data at any time, and the machining accuracy of each inner cone surface is visible, ensuring that the error control range of the inner cone angle is ± 0.8 °, and the axial grinding tolerance of the sealing circle is 0.075 μm. This is a specialized three coordinate measuring instrument detection device designed by AAK based on the structural characteristics of the valve cage. This is not only a trick, but also a 100% leak free skill. Most of the hydraulic cartridge valve manufacturers in Ningbo can only imagine, but may not be able to do it.
AAK hydraulic pressure control valve, with precision tips, no leakage, you can also give it a try!
