Walt placed an order for 1000 hydraulic threaded cartridge valves at one time last week, which surprised me. Three years ago, I met Walt from an American company at the Shanghai PTC exhibition. He communicated with us at our booth for more than half an hour. After the exhibition, Walt sent an email saying that his company happened to have a newly developed hydraulic equipment, which needs to use hydraulic threaded cartridge valves. He asked AAK to urgently provide 30 samples of hydraulic threaded cartridge valves according to his drawings. AAK sent out 30 hydraulic threaded cartridge valves after 25 days. After this, there was no inquiry for any hydraulic threaded cartridge valves from him. Half a year later, Walt sent a new test order of 40pcs for another new hydraulic threaded cartridge valve. Same as last time, there is no further news after delivery. In this way, we just received 2 test orders in about 2 years.

 

I thought that there should be a mistake on the quantity of this large order of hydraulic threaded cartridge valve this time. After several rounds of emails, we know the story for this hydraulic threaded cartridge valve. Their company has only begun to purchase hydraulic valves from China in recent 3 years. For the hydraulic threaded cartridge valves purchased at the beginning, there are always complaints from customers after a period of time, such as leakage or jamming, insensitive opening and closing or serious wear and tear, etc. In the past 2 years, Walt also tried samples from more than 20 hydraulic valve manufacturers. The same problems still occur after each replacement. Only AAK hydraulic threaded cartridge valves have not received a complaint.

 

Walt compared more than 20 suppliers for 2 years, and only AAK hydraulic threaded cartridge valves had no complaints. This time, he strongly suggested his boss that the future hydraulic threaded cartridge valves can only be purchased from AAK. His boss also wants to know why AAK can ensure that there are no complaints about the hydraulic threaded cartridge valves.

 

AAK hydraulic valve not only has the CNC machining center imported from Switzerland, but also has its own upgraded and refitted independent fixtures, which eliminates man-made errors. At the same time, we have accurately controlled every detail of the processing, production, assembly, inspection and packaging of each hydraulic threaded cartridge valve, which has surpassed the vast majority of domestic peers.

 

Firstly, AAK will divide the installed products into several assembly units according to the structure and process characteristics of the hydraulic valve, reduce the single parts entering the general assembly as much as possible, and ensure the reasonable assembly sequence and specified assembly accuracy of the hydraulic valve. All parts will be accurately measured, strictly inspected and tested before and after the general assembly of the hydraulic threaded cartridge valve.

 

Secondly, AAK adopts the matching method for assembly, which will divide the parts into several groups according to the strict size range, and then assemble the corresponding matching parts together to achieve the required assembly accuracy.

 

Finally, after assembly, check whether there is surplus or lack of parts, whether each connecting part is loose and skewed, and whether the residue of sealing belt on cone plug is removed. At the same time, test each hydraulic threaded cartridge valve, including leakage, flexibility, opening and closing performance, etc.

 

AAK hydraulic threaded cartridge valve is free of complaint. Welcome to have a small try!
