AAK Hydraulic Directional Control Valve Service Life 2 Million times

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.

AAK hydraulic directional control valves are also tested for a service life of
more than 2 million times, to ensure that its performance exceeds its lifespan.
AAK has independently developed durability testing equipment that complies with
the NFPA/T2.6.1 standard and performs fatigue testing on valves. AAK's
durability testing equipment has 5 testing stations that can operate
independently of each other, and each testing area is equipped with hydraulic
and electrical sources that help with valve fatigue testing. The testing
efficiency has been improved by more than 60% compared to peers.

AAK hydraulic directional control valve, with a service life of over 2 million
times, you can also give it a try!
