For Hydraulic Directional Control Valve with a service life of over 2 million ti

Giles is from Greece, and has been successful in purchasing hydraulic valves from China, but recently he was greatly affected by a hydraulic directional control valve. In the second half of 2021, their paper cutting machine needed the use of hydraulic directional control valves. Giles purchased it from a hydraulic directional control valve manufacturer in Ningbo China. Half a year later, a customer complained that the hydraulic directional control valve was leaking and causing abnormalities in the paper cutting machine. The original hydraulic directional control valve manufacturer stated that its service life was over and could only be replaced with new ones. Giles was helpless and had to search for a new manufacturer of hydraulic directional control valves with a service life of more than 2 million times. After a week, there was no result.

Giles sent an email to AAK and the first sentence is like this: he was surprised by AAK's ranking on Google and on the homepage of China hydraulic valve manufacturers. I understood that he found the AAK hydraulic valves on Google. After communication, it was learned that Giles needs hydraulic directional control valves with a service life of over 2 million times. I provided two customer cases for his reference. No correct nonsense, only existing facts that AAK is far ahead of its peers, the other hydraulic cartridge valve manufacturers in China. Facts are power. Giles requested AAK samples on the third day. After 55 days, AAK sent 30 samples of hydraulic directional control valves. Last week, Giles sent us a PO for 1,000 hydraulic directional control valves. Their technical department has tested the hydraulic directional control valve samples of AAK for 1 year, and there are no leaks. AAK hydraulic directional control valve samples have met the requirement of a service life of more than 2 million times, and he now only believes in AAK.

In fact, achieving a hydraulic directional control valve with a service life of over 2 million times is not difficult. AAK adopts a 2+1 mode, first passing through 2 steps, and finally batch testing the service life of the hydraulic directional control valves.
1. Increase the procurement cost of materials and accessories by more than 15% to ensure that the materials pass their lifespan first.
2. Increase processing costs by more than 10%, increase the number of quality inspectors for key processes, assign responsibilities to individuals, and ensure that functions pass the lifespan first.
