AAK Hydraulic valve block uses Swiss technology, free of leakage

Smith is the head purchasing of a hydraulic company from California. His
purchasing of hydraulic valves in recent years has been smooth. In the last
hydraulic valve block order, the parameters were normal when the hydraulic
valve block approval sample was tested for the first time, but there was oil
leakage in the second test on the hydraulic valve block. After rechecking, the
oil leaked again in the third test on the hydraulic valve block. Smith
communicated with the hydraulic valve block manufacturer for many times but
without results. The manufacturer said that this is the traditional sealing
process of hydraulic valve block, Smith should either accept it as is or cancel
the order. Smith knew that the delivery date confirmed with the customer was
due in 1 month, so it was urgent to find a new hydraulic valve block
manufacturer to replace the current one.

Smith checked the sealing process of no less than 20 hydraulic valve block
manufacturers. They all adopted the traditional sealing method of hexagonal
plug combined with and sealing gasket. Smith knew that although this sealing
method is simple to operate, it has very high requirements for tightening
torque. When the torque parameters are not up to standard, the hydraulic valve
block is easy to leak. In order to prevent leakage, some hydraulic valve block
manufacturers apply anaerobic glue on the threads. During operation, the
particles of anaerobic glue fall into the valve hole, causing oil pollution or
valve jamming of the hydraulic valve block.

The delivery date is approaching day by day, but the new qualified hydraulic
valve block manufacturer has not been found yet. Smith is worried and asks
around. His friend Caleb gave him the contact information of AAK hydraulic
valve. Caleb is also our hydraulic valve customer in the United States. He
suggested Smith contact AAK, and told him that AAK hydraulic valve exports to
European and American markets all year round and has some unique R & D
processes. Perhaps AAK will be different in the sealing treatment process of
hydraulic valve block.

Smith directly sent us the hydraulic valve block drawing and required that the
traditional sealing technology should not be used. A week later, AAK sent the
hydraulic valve block sample successfully. Two weeks later, Smith informed AAK
by email that the parameters of AAK hydraulic valve block were fully up to
standard after 3 tests, and there was still no leakage after the 4th and 5th
tests.

Smith is very curious about how the sealing process of AAK hydraulic valve
block is different from that of other hydraulic valve manufacturers?

The vast majority of hydraulic valve manufacturers fail to seal the hydraulic
valve block in place because they stick to the rules in technology. 6 years
ago, AAK was eliminated by the customer due to the leakage of the traditional
sealing technology of the hydraulic valve block. After that, we decided to
adopt the new technology. AAK has introduced new sealing technology and MB
Series plugs of KVT company in Switzerland as early as 5 years ago. It mainly
forms a solid sealing surface in between the metal parts in the way of
expansion, extrusion and bite, so as to 100% avoid oil leakage of the hydraulic
valve block, and fundamentally solve the difficulty of high-pressure sealing of
the hydraulic valve block. At the same time, the pollution is small and the
stability of the hydraulic valve block is stronger.

AAK Hydraulic valve block has the sealing technology comparable with Swiss
technology, is pollution and leakage free, you are welcome to have a small try!
