Erop comes from Russia, and started purchasing hydraulic cartridge valves from Ningbo 2 years ago. In the second half of last year, they customized a hydraulic cartridge valve for use in their power unit equipment. After debugging, it was found that the equipment has 3 disadvantages: vibration, high impact, and high energy consumption. Their engineer optimized the hydraulic system, but the customized hydraulic cartridge valve did not work well. After 3 times of revision, the sample still failed to match the equipment requirements, which made Erop very upset.

 

Erop found AAK in B2B, browsed AAK website for more than 5 minutes, and left a message: Can the AAK hydraulic cartridge valve solve the problems of vibration, high impact, and high energy consumption in the hydraulic power unit? This question is too big. It is hard to determine if it can be solved solely by replacing hydraulic cartridge valves. After communication, it was learned that his customized hydraulic cartridge valve was unable to upgrade their equipment.

 

Based on the schematic diagram of the power unit system provided by Erop and the anatomical diagram of the original hydraulic cartridge valve manufacturer, AAK engineers have determined that the valve spool of the original hydraulic cartridge valve is under unbalanced force and is a hidden danger, AAK can make samples to solve the hidden dangers of equipment vibration and impact, but not very certain to solve the energy consumption problem. Erop may not have a better choice, and asked AAK to make samples after a week later. After 45 days, AAK sent out 10 samples of hydraulic cartridge valves.

 

4 weeks later, Erop informed us that the equipment trial run was successful. Their engineers were very satisfied with the 2 advantages of AAK hydraulic cartridge valves (no vibration, low impact). Their hydraulic power unit energy consumption also decreased by more than 10%. Compared to similar devices in the market, their equipment highlighted 3 major selling points (low vibration, low impact, and energy consumption reduction).

 

The concept of AAK hydraulic cartridge valve is that the original valve spool is in an open state and cannot be closed, which is the root cause of impact and vibration. If the valve spool is closed or opened, a large amount of oil is required, which also leads to high energy consumption. We made clever moves around the valve spool. The force area on both sides of the AAK hydraulic cartridge valve spool is equal and the force is balanced. The valve spool is not affected by pressure, shortening the opening and closing time, and the movement state of the valve spool is easy to adjust and control, reducing impact and vibration, and reducing noise.

 

1. The valve spool is arranged in the valve chamber of the valve sleeve and can slide. There are axial and radial main oil ports in the front of the valve chamber, and the rear of the valve chamber is separated into a pilot controlled opening chamber and a pilot controlled closing chamber by a convex plate located on the outer side of the rear end of the valve spool.

 

2. The spring is installed in the spring installation chamber at the rear end of the valve spool, and there is a ring shaped extension at the rear end of the boss, and the outer diameter is smaller than the inner diameter of the valve chamber. The rear end of the valve chamber is fixed with a guide sleeve that allows the ring shaped extension to slide through it.

 

3. The valve chamber between the boss and the guide sleeve forms a pilot controlled closing chamber.

 

AAK hydraulic cartridge valve, 2 advantages, no vibration, low impact, you can also give it a try!
