AAK Hydraulic Counterbalance Valve Saving Energy for 30%

Milan from the Netherlands is an old customer of AAK. He purchased many non-
standard customized hydraulic counterbalance valves from AAK. In March this
year, Milan asked by email: can AAK design hydraulic counterbalance valves to
reduce the energy consumption of equipment? It was learned that a hydraulic
elevator developed by their company focused on the selling point of "low energy
consumption and high efficiency", but after equipment commissioning, the energy
consumption was not as good as expected and could not be promoted to the
market. Their engineer knew that it was the problem of the hydraulic
counterbalance valves, but there was no improvement after making efforts for
several times. Milan contacted a number of hydraulic counterbalance valve
manufacturers, but there was no gain. He was very anxious.

According to Milan's hydraulic schematic diagram and the original design
drawing of the hydraulic counterbalance valve, AAK engineers analyzed that the
problem really lies in the control of the hydraulic counterbalance valves. AAK
can redesign the hydraulic counterbalance valve with 90% confidence. Milan
seems to have no better choice. He paid $2,000 development fee. After 50 days,
AAK sent 20 samples of hydraulic counterbalance valves.

Last week, Milan sent an order for 600 hydraulic counterbalance valves. At the
same time, he informed that based on AAK newly designed variable pilot ratio
hydraulic counterbalance valve, their engineer adjusted the working conditions
of the equipment, improved the hydraulic principle, and saved more than 30% of
the energy consumption of the hydraulic elevator. The promotion at the
exhibition was also very smooth, the booking was hot, and their whole team was
happy. But I'm a little unhappy. The price of Milan's regular order has dropped
by 40% compared with the trial order. I told him that you can't let me "earn
some money from selling cabbage with the heart of selling Heroin". Milan may
also be amused, and directly revised it to the original price, only stressing
the need to ship on time.

How do AAK engineers design variable pilot ratio hydraulic counterbalance
valves? In fact, it is simply based on Milan's energy consumption pain point,
fight to the end. The variable pilot ratio hydraulic counterbalance valve is an
innovation from the mechanical structure of the valve, which utilizes the
characteristics of variable pilot ratio and pilot pressure. When stable, a low
pilot ratio is used, and when unstable, a high pilot ratio is executed.
Compared with the conventional standard hydraulic counterbalance valves, the
pilot pressure required for full opening can be 30% lower under the same
pressure and flow. At the same time, AAK's variable pilot ratio hydraulic
counterbalance valve can keep the oil cylinder and motor moving more smoothly
and quickly. Compared with the original hydraulic counterbalance valve, the
energy consumption can be reduced by 30%.

Milan privately told that as long as the purchase of the hydraulic
counterbalance valve was successfully completed this time, he could be
promoted.

AAK variable pilot ratio hydraulic counterbalance valve, energy saving 30%, you
can also have a small try!
