Dual Function AAK Hydraulic Cartridge Relief Valve, helped Heller Save Cost by 6%

China [CN]

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!
