AAK Cartridge Directional Control Valve Reduced Energy Consumption by 20%

AAK hydraulic cartridge directional control valve adopts a closed unit with 4
faces, which replaces the traditional 2 faces to connect the main flow. The
flow rate can reach 760L/min, while the pressure drop is less than 7bar, and
the applicable pressure can reach 350bar. It not only improves the stability of
the hydraulic system, but also increases the energy consumption of the
equipment by at least 20%. Napoleon did not hesitate to give up the original
hydraulic cartridge directional control valve manufacturer that had cooperated
for 5 years, and chose AAK for the annual order.

For personalized customization, it does not only need to benchmark the
manufacturing quality of first-line brands, but also need the team knowing 6
aspects, including design, materials, process, technology, production line
control and testing. Not a single one can be omitted. However, most of the
hydraulic valve manufacturers only have the production capacity according to
the drawing, and use traditional technology to produce market goods, which is
difficult to meet the personalized requirements of customized equipment.

Napoleon is from a hydraulic equipment manufacturing company in Italy. Last
year, he asked me about the technical parameters of a hydraulic cartridge
directional control valve, then no further contact any more. At the beginning
of the year, they customized a hydraulic casting machine for a customer. During
debugging, they found that the stability of the equipment was not high, and the
operation would lag after it was started. Their engineer judged that the
hydraulic cartridge directional control valve was unqualified. Napoleon is very
cautious in purchasing. For this hydraulic cartridge directional control valve,
he specially selected a supplier who has cooperated for 5 years to make
samples. The original manufacturer retested all parameters of the hydraulic
cartridge directional control valve, but found no abnormality. Napoleon guessed
that the original design may have hidden dangers, but the original manufacturer
has no ability to modify the design.

Napoleon came to me again and informed me of the current dilemma of the
hydraulic cartridge directional control valve. AAK engineer analyzed the
drawings of the hydraulic cartridge directional control valve and the video of
the equipment operation, judged that the original design had hidden dangers,
and also had an improvement plan. We suggest making samples directly. After 45
days, AAK sent 10 samples of hydraulic cartridge directional control valves. 2
weeks later, Napoleon informed that after installing AAK hydraulic cartridge
directional control valves, the hydraulic system of the hydraulic casting
machine was stable. After it was started, there was no lag, and the energy
consumption of the equipment reduced by more than 20%. Their customer was very
satisfied. Their company also plans to promote this hydraulic casting machine,
and asked me to wait for the annual order for the hydraulic cartridge
directional control valve.

The design of the original hydraulic cartridge directional control valve adopts
the traditional closed unit with 2 sides, one side is connected with the main
flow, and the other side is used for control. The position of the closed unit
can only be determined according to the pressure ratio between the main flow
interface and the control oil interface, and the opening can only depend on the
spring. The hydraulic system of the customized equipment of customer is a
little special. When such a hydraulic cartridge directional valve is used on
the equipment, it has an impact on the stability. AAK hydraulic cartridge
directional control valve adopts a 4 face closed unit, adds 2 independent
control surfaces, and has an adjustable position "open valve" gear. When
closing the valve, there will be no delay, nor the force of the spring, to
ensure no lag after opening. AAK hydraulic cartridge directional control valve
not only adds new functions, but also improves the original functions. The flow
rate can reach 760L/min, while the pressure drop is less than 7bar, and the
applicable pressure can reach 350bar. The hydraulic system of the equipment is
stable, and the energy consumption is reduced by at least 20%.

AAK hydraulic cartridge directional control valve is customized, which is
incomparable to the peers. You can also have a small try!
