Detailed Description

Last week Grossman placed an order for 1,500 hydraulic cartridge valves at one time. I'm not surprised at all. At the Shanghai PTC exhibition the year before last, I met Grossman from a Russian company and talked for more than 30 minutes at the exhibition. After the exhibition, Grossman informed by email that a newly developed hydraulic equipment of their company needs hydraulic cartridge valves, and 20 hydraulic cartridge valves from AAK were tested. This is a non-standard customized hydraulic cartridge valve. After we delivered the goods, Grossman didn't send any email to feed back the situation of AAK goods for half a year. A year later, Grossman placed the reorder of 200 hydraulic cartridge valves of the same model, and there was also no news after delivery. In 2 years, there were only two small orders of hydraulic cartridge valves, but I have a feeling that Grossman is further deeply testing AAK hydraulic cartridge valves. 

 

It was not until last week when there was a large order for hydraulic cartridge valves placed, Grossman then started to describe the ups and downs of purchasing hydraulic cartridge valves in Ningbo. In the past 2 years, Grossman found more than 20 hydraulic cartridge valve manufacturers for sample testing and was cheated by some new hydraulic cartridge valve manufacturers. The quality of the test order was OK, but the reorder was complained by customer. For hydraulic cartridge valves purchased from some other factories, there were always complaints after a period of time, such as several leaks or jamming, insensitive opening and closing or serious wear etc.

 

The 2 batches of hydraulic cartridge valves from AAK have not received any complaint in 2 years, which is why he decided to order large quantities of hydraulic cartridge valves from AAK. After 2 years of comparison among more than 20 hydraulic valve manufacturers, Grossman found that only AAK hydraulic cartridge valves are 100% qualified. His boss also agreed that the future hydraulic cartridge valves will only be purchased from AAK.

 

No customer complaints with AAK hydraulic cartridge valves, that is because AAK has 3 advantages. There may be no second manufacturer in Ningbo who can have the following 3 points at the same time.

 

1. AAK hydraulic valve has high-precision CNC machining centers, machine tools and other equipment imported from Switzerland, as well as various independent fixtures upgraded and refitted by himself, which eliminates human errors. At the same time, the management of every detail of the processing, production, assembly, inspection and packaging of each hydraulic cartridge valve has been accurately controlled.

 

2. AAK uses pneumatic measuring instrument to test the accuracy of each processed valve sleeve, while most manufacturers use sampling test. During the assembly of accessories, the accuracy of the fit clearance between each valve spool and valve sleeve is tested again with a pneumatic measuring instrument.

 

3. After assembly, carefully check whether the accessories are complete, and test each hydraulic cartridge valve, including leakage, flexibility, opening and closing performance etc.

 

AAK hydraulic cartridge valves have conquered Russian customer with 3 facts leading domestic peers. You can also try one order.
