AAK Directional Control Cartridge Valve 3 Optimizations 2 Benefits

Eugenia is from Belarus and has purchased hydraulic cartridge valves from AAK
for 3 years. In the second half of last year, they developed a hydraulic power
unit. Their customer asked for a price reduction of 15% to meet the market
demand. Eugenia required the original hydraulic directional control cartridge
valve manufacturer and his hydraulic component suppliers to reduce the price
simultaneously, but it did not meet 15%. The boss was unhappy. Eugenia was very
upset.

Eugenia contacted me. As soon as I heard about the price reduction request of
the hydraulic directional control cartridge valve, I gave up directly. 7 days
later, Eugenia came to me again and asked if we could reduce the hydraulic
components and combine them into a new hydraulic unit. This aroused my
interest. According to the schematic diagram of the hydraulic system provided
by Eugenia, AAK engineers found that there are multiple directional control
cartridge valves in the equipment, which not only makes the flow path complex,
but also increases the cost. Is it possible to optimize the hydraulic
directional control cartridge valve in the system to replace the function of
the multiple valves, and reduce the cost? Eugenia requested AAK to try samples.
After 45 days, AAK sent 12 samples of hydraulic directional control cartridge
valves.

2 weeks later, Eugenia informed us that after replacing those hydraulic
components with AAK hydraulic directional control cartridge valve, the function
of the hydraulic unit was not affected. AAK hydraulic directional control
cartridge valve controls the flow of the oil port through the opening size of
the hydraulic control oil port, simplifies the hydraulic oil circuit, reduces
energy consumption by a little, and reduces the overall procurement cost by 20-
25%. The use of AAK hydraulic directional control cartridge valve brings her 2
additional benefits. Can Eugenia be unhappy?

1. In the valve body of the hydraulic directional control cartridge valve,
there are left and right through valve holes and are connected with the valve
spool in a sliding way. On the side of the valve body, there are 3 annular
grooves from left to right. Each annular groove has an oil inlet connected with
the valve hole and a flow hole. The screw sleeve is installed at the left end
of the valve body and is connected with the transmission rod at the left end of
the valve element.

2. There is a screw plug at the left end of the hydraulic directional control
cartridge valve hole, which is sleeved on the transmission rod, and the return
spring is sleeved on the outside of the transmission rod. There is a first
spring seat on the transmission rod, and its right end extends into the valve
hole through the screw plug. When the valve spool moves to the left, the return
spring is compressed through the first spring seat.

3. There is a second spring seat sleeved on the transmission rod between the
left end of the return spring and the plug. The left end of the transmission
rod has a shoulder. When the valve spool drives the transmission rod to move to
the right, the return spring is compressed through the second spring seat. The
outer side of the screw sleeve is provided with a fourth annular groove, and
the fourth annular groove is provided with a hydraulic control oil port
connected with the mounting hole.
