AAK Hydraulic Pressure Control Valve Specially for Off Center Cavity

Galeno, from Spain, has cooperated with AAK for 2 years and tried several non-
standard customized hydraulic cartridge pressure control valves. At the
beginning of this year, they developed a hydraulic windlass to be promoted in
the exhibition. They need a hydraulic cartridge pressure control valve for the
hydraulic system of the windlass. Galeno got samples from local manufacturer of
hydraulic cartridge pressure control valves. After the commissioning, the
pressure control of the equipment is unstable. The engineer judged that the
cavity of the hydraulic manifold was off center, resulting in unstable pressure
control of the hydraulic cartridge pressure control valve after being screwed
in. The hydraulic manifold manufacturer needed 2 months to re sample, but the
exhibition was less than 50 days, Galeno was worried.

Galeno tried to find a new hydraulic manifold manufacturer. When I received
his inquiry for hydraulic manifold, I was a bit surprise. After communication,
I learned that he encountered unstable pressure control of hydraulic cartridge
pressure control valve. I told him that under similar circumstances, it is not
necessary to re produce the hydraulic manifold. 1 year ago, AAK developed a
specially designed hydraulic cartridge pressure control valve, which was
specially designed to coordinate with the off center cavity of the hydraulic
manifold. Galeno compared the technical parameters of the AAK hydraulic
cartridge pressure control valve and it basically matched the hydraulic system
of their hydraulic windlass.

2 weeks after the sample was sent, Galeno informed that the installation of AAK
hydraulic cartridge pressure control valve to the equipment was smooth, and the
machine test was normal. The prototype was already on the way to the
exhibition. His boss was very satisfied with this urgent solution. I told him
that the unique design of AAK hydraulic cartridge pressure control valve was
beyond the imagination of most hydraulic valve manufacturers. We got
inspiration from an old customer. The customer purchased the hydraulic manifold
block and the hydraulic cartridge pressure control valve from 2 different
factories. After the installation was abnormal, the two factories passed the
buck. At that time, we imagined whether it was possible to let the hydraulic
cartridge pressure control valve match the hydraulic manifold block with off
center cavity, or vice versa.

AAK technical team has figured out that the middle thread can be used in the
hydraulic cartridge pressure control valve, that is, the floating structure.
The connection area of the port can be optimized, and the center of the thread
position can be positioned to maximize the flow capacity and minimize the
eccentric influence of the hydraulic manifold block cavity. The diameter of the
valve shoulder at the thread provides guidance to ensure the accurate alignment
of the thread. The space of the valve shoulder is sufficient, which increases
the flexibility of the installation torque and is not easy to damage the
torque. The installation torque space can minimize the impact of hydraulic
pressure on the valve and is conducive to pressure control.

AAK hydraulic cartridge pressure control valve, specially designed to match the
hydraulic manifold block with off center cavity, you can also have a small try!
