Dual Function AAK Hydraulic Cartridge Relief Valve, helped Heller Save Cost

AAK used 3 methods to directly replace a cartridge check valve and a relief
valve in the hydraulic system with one hydraulic cartridge relief valve, which
not only facilitated installation, but also integrated the functions of the two
valves. The manufacturing cost of the hydraulic unit was reduced by 6%, and
helped Heller win the order from customer successfully.

Heller is from Indonesia. In the second half of last year, their old customer
customized a hydraulic power unit. The hydraulic cartridge relief valve used
was produced by a cartridge valve manufacturer who has cooperated with them for
5 years. The equipment was successfully debugged, and the customer recognized
it after trial use. However, after comparing with the market, the customer
asked for a 5% reduction in the price of the equipment. Heller tried to reduce
the purchase cost, but failed. Their engineers said that they could only
optimize the hydraulic manifold to reduce the cost, but it was too late. The
order has been holded for 2 weeks, and Heller was worried.

Heller found AAK on Google and stayed on AAK hydraulic valve website for more
than 10 minutes. Perhaps the customer cases of optimizing hydraulic cartridge
valves stimulated him. He sent an email asking: How long does it take to
optimize the original hydraulic manifold and sample? After communication, I
learned Heller's dilemma. According to the schematic diagram of his power unit
system, AAK engineers found that it was not necessary to adjust the original
hydraulic manifold. There were 2 types of valves (check valve and relief valve)
in the hydrostatic circuit of the system. If the functions of the 2 types of
cartridge valves were integrated, the cost can be saved, and there would be no
need for big change for the hydraulic manifold. Heller sent the sample order of
hydraulic cartridge relief valve on the 3rd day after learning about the AAK
scheme. After 50 days, AAK sent 3 hydraulic cartridge relief valve samples.

3 weeks later, Heller emailed that the commissioning of the dual function AAK
hydraulic cartridge relief valve was smooth, and the overall purchase cost was
reduced by 6%. Not only did they solve the pending order for the equipment, but
their company's profits were also increased. The mind of AAK engineers
benefited from more than 10 years of training in German HAWE. AAK achieved a
dual function hydraulic cartridge relief valve with 3 skills.

1. This hydraulic cartridge relief valve is equipped with 3 separate fluid
channels, which are respectively connected with the high pressure pipeline
fluid, the low pressure side fluid and the feeding pressure pipeline fluid in
the system.

2. The damper is added to strengthen the positive damping of the overflow
function and realize reasonable control of the flow direction, which can
replace the cartridge check valve function.

3. Connect the first and second lifting valve spools with a spring, and use the
spring and lifting valve spool to make the fluid flow through the specified
route as required to realize the dual functions of check and overflow.

AAK hydraulic cartridge relief valve, integrating 2 functions into 1, you can
also try a small order!
